What is 0Cr18Ni9

304 (0Cr18Ni9)

China standard 0Cr18Ni9, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot workability such as stamping and bending, no heat treatment hardening phenomenon (non-magnetic, use temperature -196 °C~800°C).

Applications: household goods, auto parts, medical equipment, building materials, chemicals, food industry, agriculture, ship parts.

D11

D11: The performance of this steel grade is equivalent to that of 304. It replaces 304 in many fields, especially in the fields of printing and dyeing machinery, chemical industry and machinery manufacturing.

In Japan, it has been widely used instead of 304. The results of the use are well reflected and the price is low. It is nearly RMB 1,000/ton cheaper than 304, which is very cost-effective.

Applications: household items (1, 2 types of tableware, kitchen cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, molded products), medical equipment, building materials, chemicals, food industry, agriculture, ship parts.

304L (00Cr19Ni10)

00Cr19Ni10 is a low C 304 steel. In general, its corrosion resistance is similar to that of 304 steel, but it has excellent resistance to intergranular corrosion after welding or stress relief; it can be maintained without heat treatment. Good corrosion resistance, use temperature -196 ° C ~ 800 ° C for high resistance to intergranular corrosion, coal, oil industry field open-air machines, building materials heat-resistant parts and heat treatment difficult parts.

304N1 (0Cr19Ni9N)

0Cr19Ni9N is a nitrogen-containing stainless steel. Nitrogen is added to increase the strength of steel. 305 and 384 stainless steels contain high nickel and have a low work hardening rate, which is suitable for places where high cold formability is required.

On the basis of 304, S, Mn, and yttrium are added to prevent plasticity reduction, improve steel strength, and improve pitting corrosion resistance, crevice corrosion and crevice corrosion performance.

Applications: It is the most widely used as stainless steel. It is suitable for petroleum and chemical equipment. It is suitable for the manufacture of acid pipelines and containers.
