304(1.4301)/304L(1.4307)/304H(1.4948) STAINLESS STEEL
Stainless Steel Grade 304H includes a high carbon content making the steel more suitable for utilization in applications where high temperatures are available. The benefit of this grade is that it is an austenitic chromium-nickel steel alloy as well as the greater carbon content distribute to increased tensile and yield strength. The material is recommended for utilizing in ASME pressure vessels in working service above 525° C because of the grade's heat resistant properties.
What is the difference between 304 and 304DDQ stainless steel?
Compared with 304, the CR content of 304DQ is increased by half to one, and the polishing is better. Compared with 304, the content of 304DDQ has not changed. The content of NI is increased by half to one, and the deep drawing and deep drawing are better. “Soft material” but poor polishing performance.
304DDQ stainless steel uses a special process to increase the chromium content of 304 stainless steel by 2 points (304 steel plate is 18/8, 304 DDQ is 18/10), which means that the content of nickel (Ni) in 304 stainless steel is 18%, and chromium ( The content of Cr) is 8%; the content of nickel (Ni) in the improved 304DDQ stainless steel is 18%, and the content of chromium (Cr) is 10%; the steel plate has high brightness, no discoloration, and beautiful appearance, but also has the best Good ductility, toughness, and corrosion resistance.
