The chemical composition of SS316 (ASTM standard) and SUS316 (JIS standard) is basically the same, but the strength of SS316 may be improved by adjusting the nitrogen content, and the lower limit of t

SS304 (AISI 304) is the most commonly used stainless steel in the manufacture of other stainless steel materials and is usually purchased in the cold or annealed condition. Similar to SUS304, SS304 al

304 stainless steel pipe weld flaw detection service is a professional service for defect detection of austenitic stainless steel welds through ultrasonic (UT), X-ray (RT) or penetrant testing (PT) an

SUS304 stainless steel annealed coil eliminates internal stress through precision annealing process, improves ductility and surface finish, and is widely used in construction, chemical industry, medic

1.4301 stainless steel pipe is austenitic stainless steel, non-magnetic, can be cold-processed and strengthened, short-term temperature resistance ≤800℃, long-term continuous use recommended ≤700℃.

304 stainless steel bar is austenitic stainless steel, non-magnetic, and can be cold-processed and strengthened. It is resistant to corrosion by the atmosphere, water, weak acids and alkalis (such as

17-4PH Precipitation Hardening Stainless Steel has a yield strength of 700–1300 MPa, which is better than martensitic stainless steel (such as 400 series) and close to 304 stainless steel.

AISI 321 (1.4541, UNS S32100) is an austenitic stainless steel with properties similar to AISI 304 stainless steel, but with at least five times the titanium content. This titanium mixture reduces or

316 stainless steel and 321 stainless steel are both austenitic stainless steel. The grade of 316 stainless steel is slightly higher than that of 321 stainless steel. This is because 316 stainless ste

321 (UNS S32100) and 347 (UNS S34700) are both austenitic stainless steels. Intergranular corrosion is inhibited by adding stabilizing elements (titanium or niobium) and are widely used in high temper

17-4PH (UNS S17400/W.Nr:1.4542) is a precipitation hardening martensitic stainless steel, which is widely used in aerospace, petrochemical and medical equipment fields and needs to maintain long-term

ASTM A358 CL1 Stainless Steel Welded Pipe‌ is an electric fusion welded austenitic chromium-nickel stainless steel pipe specially designed for high temperature or corrosive environments. According to
