五月 20, 2019

 

Chemical composition
304 is a cover type stainless steel, 和它的材料组合物是OCr18Ni9, 316L是奥氏体不锈钢, 和它的材料组合物是OOCr12Mo2Ti.

不同的性能
该 304 钢可以抵抗硫酸的腐蚀, 磷酸, 蚁酸, 尿素, 等等.
钼的除 304 基地 316升钢制 可以显著提高其晶间耐腐蚀, 氧化应激腐蚀和焊接过程中的热裂倾向, 以及其良好的抗氯化物腐蚀. 用于纯净水, 蒸馏水, 医学, 酱, vinegar and other health requirements, medium corrosion strong occasions. The price of 316L is almost double that of 304.

Different maintenance methods
304 不锈钢: 18cr-8ni-0.08c good corrosion resistance, oxidation resistance and processing, strong oxygen resistance and acid resistance, can be stamped, can make containers, tableware, metal furniture, architectural decoration, and medical appliances. 316 不锈钢: 18cr-12ni-2.5Mo is common in seaside buildings, ships, nuclear power chemical and food equipment, 等等. It not only improves the corrosion resistance of hydroelectric acid and Marine chemicals, but also improves the corrosion resistance of brine halogen solution.

Use
304 stainless steel is mainly used for corrosion resistant containers, tableware, furniture, railings, medical equipment. 该 316 stainless steel is mainly used in the food industry, watch and watch accessories, pharmaceutical industry and surgical equipment.
