1 奥氏体形 1Cr17Mn6Ni5N 节镍钢种，代替牌号1Cr17Ni7，冷加工后具有磁性。铁道车辆用。
2 1Cr18Mn8Ni5N 节镍钢种，代替牌号1Cr18Ni9
3 1Cr17Ni7 经冷加工有高的强度。铁道车辆，传送带，螺栓螺母
4 1Cr18Ni9 经冷加工有高的强度，但伸长率比1Cr17Ni7稍差。建筑用装饰部件。
各种不锈钢材料因其物质含量不同而具备不同的特性所以耐腐蚀性也各有不同.以下就几种常用材质作简单解说:
304 是一种通用性的不锈钢，它广泛地用于制作要求良好综合性能（耐腐蚀和成型性）的设备和机件。
301 不锈钢在形变时呈现出明显的加工硬化现象，被用于要求较高强度的各种场合。 302 不锈钢实质上就是含碳量更高的304不锈钢的变种，通过冷轧可使其获得较高的强度。
302B 是一种含硅量较高的不锈钢，它具有较高的抗高温氧化性能。
303和303Se 是分别含有硫和硒的易切削不锈钢，用于主要要求易切削和表而光浩度高的场合。
303Se不锈钢也用于制作需要热镦的机件，因为在这类条件下，这种不锈钢具有良好的可热加工性。
304L 是碳含量较低的304不锈钢的变种，用于需要焊接的场合。较低的碳含量使得在靠近焊缝的热影响区中所析出的碳化物减至最少，而碳化物的析出可能导致不锈钢在某些环境中产生晶间腐蚀（焊接侵蚀）。
304N 是一种含氮的不锈钢，加氮是为了提高钢的强度。参考资料：深圳恒宇金属材料有限公司

Hengyu Metal Material Co., Ltd. was established in Shenzhen in 2002, the company is located in Shenzhen City, Guangdong Province, is a professional stainless steel R & D and production of large high-tech enterprises. I plant abundant funds, advanced technology, with a set of advanced production and quality testing equipment. Has advanced processing equipment, drawing machines, wire drawing machines, bar, profile polishing machine, Φ1.5-50mm round bar straightening machine, S5-S41 hexagonal bar straightening machine, CJK6140H-CKA6150 8 CNC machine tools, double-sided milling (automatic) 12, CY6140 general machine tools 10, C2-6130HK general machine tools 5, Saw 10, surface grinder, 12 lifting equipment (cranes 1 ton, 2 tons, 3 tons, 5 tons), 9 Article pickling line, and advanced physical and chemical detection equipment. To meet customer needs, and ensure product quality is superior to similar products in the market. The company mainly produces business (domestic and imported) varieties of stainless steel: 316 stainless steel rods, stainless steel, stainless steel rod, 316 stainless steel plate, stainless steel, 316 stainless steel wire, steel wire, stainless steel coil, stainless steel, flat steel, square steel, hexagonal rods , angle steel, stainless steel screws wire, spring wire, stainless steel wire rope, all soft lines, square pipe, rectangular pipe and other products.
Section 1 of nickel austenitic steel shaped 1Cr17Mn6Ni5N, instead of grades 1Cr17Ni7, magnetic after cold working. Railway vehicles.
2 1Cr18Mn8Ni5N section of nickel steel, instead of grades 1Cr18Ni9
3 1Cr17Ni7 high strength by cold working. Vehicle, conveyor belts, bolts and nuts
4 1Cr18Ni9 high strength by cold, but slightly lower elongation than 1Cr17Ni7. Decorative building components.
Substances in a variety of stainless steel because of their different characteristics with different corrosion resistance are so different. The following are several commonly used materials to make a simple explanation:
304 is a universal stainless steel, it is widely used to produce good overall performance requirements (corrosion resistance and formability) of equipment and parts.
301 stainless steel in the deformation time shows an obvious hardening, is used to require a higher intensity of the various occasions. 302 stainless steel, high carbon content is essentially a variant of 304 stainless steel, cold can make it through a higher intensity.
302B is a high silicon content in stainless steel, it has a high oxidation resistance.
Respectively 303 and 303Se containing sulfur and selenium cutting stainless steel, the main requirements for cutting and surface Guanghao high occasions.
Stainless steel is also used for production needs 303Se hot upsetting of parts, because in such conditions, this steel has good hot workability.
304L is a low carbon 304 stainless steel variant of the occasion for the need for welding. Lower carbon content makes it close to the weld in the heat affected zone to minimize carbide precipitation, and carbide precipitation may result in some environments, stainless steel, intergranular corrosion (weld erosion).
304N is a nitrogen-containing stainless steel, plus nitrogen is to increase the strength of steel. Reference: Metal Material Co., Ltd. Shenzhen Hengyu
