Items identifed in this catalogue as stocked items are defned as goods normally held in stock, and are subject to prior sales.Steel and Tube Stainless terms of trade are supplied at the time of opening a trading account and are available upon request. A copy of this appears on the reverse of all invoices issued. A minimum order charge may apply.All weights and dimensions provided in this catalogue are theoretical.Mill tolerances will affect actual weights (+/-). All weights in this catalogue are based on a density of stainless steel being 8000kgs/m3.Types of Stainless SteelsStainless steel is a name given to a group of steel alloys that contain more than 10.5%Chromium. Chromium has a high affinity for oxygen and forms a stable oxide flm on the surface of stainless steel.The flm is called the passive oxide layer and forms instantaneously in ordinaryatmospheres. The flm is self healing and rebuilds when it has been removed. It is this flm that gives stainless steel its corrosion resistance.AUSTENITIC GRADESWhen nickel (Ni) is added to stainless steel in sufficient quantities the crystal structure is changed from Ferrite to Austenite, hence the term Austenitic stainless steel. The basiccomposition of austenitic stainless steel is 18% chromium (Cr) and 8% Nickel (Ni). This is called 304 grade, sometimes referred to as 18/8 or 18/10. If additional corrosion resistanceis required 2% molybdenum (Mo) is added to form grade 316.DESCRIPTIONS AND GENERAL USES200 Series (Indent Only)The 200-series is a technically valid family of stainless steels but, like all stainless steel grades, they have their limitations. Because the 200-series grades are austenitic, they are not magnetic and are therefore very difficult to distinguish from the widely used 300-series grades. Most growth in 200-series use over recent years has been in low-nickeland therefore low-chromium versions which have less corrosion resistance than 304. Theend result has been corrosion failures in some applications.302 (Indent Only)This grade is the original general purpose 18/8 stainless steel (18% Chromium 8% Nickel).It has good corrosion resistance combined with good physical properties - it has excellent ductility and welding properties. Non-magnetic when annealed and becomes slightly magnetic when cold worked.303 (Indent Only)Especially developed for machining - specially where it involves extensive machining in automatic screw machines. Sulphur or Selenium is added to give excellent freemachining and non seizing properties. As Sulphur or Selenium is added corrosionresistance is lower than T304. T303 is not recommended for welding. Non-magnetic when annealed but becomes slightly magnetic when cold worked.304The most widely used stainless steel with the best all round performance. Its carboncontent is lower and its corrosion after welding resistance is higher than T302. It is less susceptible to intergranular corrosion after welding. Non magnetic but slightly magnetic when cold worked.67304LA low carbon stainless steel with general corrosion resistance like T304, but with superior resistance to intergranular corrosion following welding or stress relieving.Highly recommended for parts which are fabricated by welding and which can not be annealed. Generally limited to temperatures up to 426C. The physical properties and thermal treatments of T304L are similar but not identical to T304. Non magnetic when annealed but slightly magnetic when cold worked.310S (Indent Only)310S has been developed for high temperature service where high creep strength is required. Max service temp is around 1100C but it is not recommended for applicationsof prolonged service as it may become brittle. Non magnetic when annealed or cold worked.316Also known as Marine grade stainless steel. T316 has 2-3% Molybdenum which improvescorrosion resistance. T316 has superior corrosion resistance to other austenitic steels when exposed to many types of chemical corrodents as well as marine environments-T316 also has applications in the chemical, textile, and paper industries. It has betterstrength and creep resistance at high temperatures than T304 and greater workhardening properties. Non magnetic but slightly magnetic when cold worked.316LHas lower carbon than T316, with corrosion resistance similar to T316 but superiorresistance to intergranular corrosion following welding or stress relieving. It is recommended for parts which cannot be subsequently annealed. Service temperaturesup to 426C. The physical properties and thermal treatments of type 316L are similar butnot identical to type 316. Non-magnetic when annealed but slightly magnetic when cold worked.321 (Indent Only)Basically 302 (basic 18/8) stabilised by the addition of Titanium to fve times the carboncontent. This prevents intergranular corrosion and offers scale resistance at highertemperatures up to 850C. Corrosion resistance is lower than 304. Not recommendedfor bright/mirror polishing. Non-magnetic when annealed but slightly magnetic when cold worked.904L (Indent Only)High resistance to general corrosion, e.g Sulphuric and acetic acids, crevice corrosion,stress corrosion, pitting in chlorine bearing solutions. Good weldability.Types of Stainless Steels [Contd.]8MARTENSITIC GRADESThis grade contains 12%-18% Chromium and 0.08%-1.00% carbon. The high carboncontent allows the stainless steel to respond well to heat treatment to give variousmechanical strengths such as hardness. However the carbon is detrimental when welding and care must be taken.DESCRIPTIONS AND GENERAL USES409 (Indent Only)Type 409 is general purpose construction stainless steel. Primarily intended forautomotive exhaust systems and in other applications where appearance is secondary to mechanical and corrosion resistance.410 (Indent Only)Type 410 is the general purpose corrosion and heat resisting martensitic stainless steel. It has good corrosion resistance and can be easily forged and machined. But it is not suitable under severe corrosion enviroments. It is magnetic in all conditions. Main use is for stainless steel cutlery.420 (Indent Only)Type 420 has a higher carbon content than 410 to increase hardness to a maximum of approx 500 Brinell. It has optimum corrosion resisting qualitities in the hardened and tempered conditions. Type 420 is magnetic in all conditions.431 (Indent Only)Type 431 is a nickel bearing martensitic stainless steel designed for heat treatment to the highest mechanical properties. Its corrosion resistance is superior to that of type 410 and 430. Magnetic in all conditions.9FERRITIC GRADESThese are nickel free. They have varying chromium content of 12%-22% but a lowercarbon content than the Martensitic grades.The increased Chromium increases corrosion resistance at elevated temperatures,however the lack of mechanical properties due to the fact that it can not be heat treatedlimits its application.DESCRIPTIONS AND GENERAL USES430Type 430 is a corrosion and heat resisting stainless steel with superior corrosion and heat resistance compared to type 410. Type 430 is non hardenable and possessesonly mild cold working properties due to the high chromium content. Its weldabilityis excellent and does not require subsequent annealing. Magnetic in all conditions.Common uses include builders hardware, domestic appliances (driers, dishwashers) and automotive trim.DUPLEX STAINLESS STEELDuplex stainless steels have a structure of approximately equal amounts of ferrite and austenitic and therefore may be referred to as ferritic-austenitic stainless steel. The chromium varies from 18%-28% and a Nickel content of 4.5% to 8% is insufficientto develop a fully austenitic crystal structure. Most grades contain Molybdenum in the 2.5%-4%, plus a small nitrogen addition which enables both strength and pittingresistance. Common uses include applications such as heat exchanger panels and tubes, tanks and vessels where high chloride concentrations are present e.g. sea watercooling, desalination, food pickling plants and aggressive marine waters.NICKEL AS A PRICE DRIVERUnderstanding how nickel affects the price of stainless steel can be relayed as follows:-T304 has approximately 8% nickel (so 1000 kg of S/S has 80 kg of nickel)T316 has approximately 10% nickel (so 1000 kg of S/S has 100 kg of nickel)Example: If nickel is approximately NZ $50,000 / MT or NZD $50.00 /kgTherefore in:1.0 MT of T304 stainless steel the NICKEL COST is 80kg x $50 = NZD $4000 / MT ($4.00 / KG)1.0 MT of T316 stainless steel the NICKEL COST is 100 kg x $50 = NZD $5000 / MT ($5.00 / KG)Please refer to the London Metal Exchange website up to date nickel prices.Nickel is one of the key elements in determining the price of stainless steel.Other factors affecting prices include; NZD exchange rates, worldwide scrap supply and general worldwide supply and demand for stainless steel.10Coil/SheetSTAINLESS SHEET.
