904L钢板材，依不同的交货状态有可以称为904L钢板、904L开平板、904L卷板;轧制工艺的不同有可以分为904L冷轧板和904L热轧板；依厚度不同又有904L薄钢板、904L中板、904L厚板、904L特厚板之说；千奇百怪的叫法不仅仅是从常规理解上体现还体现在904L化学成分/硬度/密度等性能的差异性上，下面就让我们先对904L板材材料的叫法来个标准定义吧：
┏┳┳┳┳┳┳┳┳┳┳┳┳┳┳┳┳┳┳┳┳┳┳┳┳┓
冷轧904L|退货态|光亮表面|904L薄钢板厚度在0.2-4mm之间的钢板。
冷轧904L|退货态|光亮表面|904L薄钢板宽度在500-1400mm之间。
冷轧904L|退货态|光亮表面|904L卷板是薄钢板的另一种供货规格
热轧904L|退货态|平整表面|904L厚钢板的宽度从0.6mm-3.0mm。
热轧904L|退货态|平整表面|904L中板是厚度小于20mm的钢板，
热轧904L|退货态|平整表面|904L厚板是厚度＞20mm至60mm的钢板，
热轧904L|退货态|平整表面|904L特厚板是厚度＞60mm的钢板

下面，有关不锈钢分类成分及性能介绍：
904L stainless steel stockholders and suppliers, delivering to the whole of the UK. China JT Metal are suppliers and stockholders of 904L stainless steel bar andplate. This grade is an austenitic stainless steel specification offering moderate to high corrosion resistance. Its high alloy composition offers good resistance to pttingand corrosion in a wide range of environments. The low carbon content of 904L improves its welding characteristics. The chromium, molybdenum and nickel contentsof 904L provide a better chloride pitting corrosion resistance than that of 316 stainless in many environments.

Form of Supply | China JT Metal are suppliers and stockholders of round bar. Also available is UNS 904L plasma cut duplex stainless plate and sheet. UNS S31803 duplex stainless steel ground steel bar can be supplied, providing a high quality stainless precision ground diameter bar to close tolerances. |
Plate | Diameter |
Applications | UNS 904L duplex can be used successfully as an alternative to standard stainless steel specifications in applications where higher strength and resistance to stress corrosion cracking is required. Widely used in the brewing, power generation, marine, petrochemical and chemical engineering industries. Typical applications include bushes, flanges, shafts and fasteners. |
Corrosion Resistance | UNS 904L is resistant to intergranular corrosion. It has better corrosion resistance than that of other austenitic stainless grades such as 316, with higher resistance to stress corrosion cracking to that of either 304 or 316 stainless grades. Pitting corrosion and crevice corrosion is higher than that of 316. Due to its higher corrosion resistance UNS S31803 has better fatigue strength in corrosive environments than that of other austenitic stainless steel specifications. |
Welding | UNS 904L (1.4462, F51) has good weldability similar to that of other stainless steel types. Low thermal expansion reduces residual stresses after welding. Use duplex welding electrodes similar to that of the parent steel when welding UNS 904L. Electric arc welding processes are suitable though oxyacetylene welding is not recommended due to the possibility of carbon pick up in the weld area of the UNS 904L. Whilst post weld annealing is not a requirement for many applications it will give optimum corrosion resistance in severe service conditions. We recommend you contact your welding consumables supplier who should provide you full assistance and information of welding UNS 904L duplex. |

Heat Treatment | UNS 904L (1.4462, F51) cannot be hardened by conventional heat treatment, though it is a work hardening steel. Duplex can be solution annealed at 1020-1100?C, water quench. |
Certification | Duplex stainless steel grade UNS 904L is available with BS EN 10204 3.1 mill certificate, please request when placing any orders. |
