What are the main differences between hot-rolled steel pipes and cold-rolled steel pipes

Keywords :hot rolled steel pipe, cold rolled steel pipe, steel pipe difference        Update : 2025-01-16        View(s) : 189

1. Cold-rolled steel pipes allow local buckling of the cross-section so that the bearing capacity after the bar buckling can be fully utilized; while hot-rolled steel pipes do not allow local buckling of the cross-section. 2. The causes of residual stress in hot-rolled steel pipes and cold-roll...

What is the difference between 2205 duplex stainless steel pipe and 304 stainless steel pipe

Keywords :2205 duplex stainless steel pipe, 304 stainless steel pipe, stainless steel pipe details        Update : 2025-01-06        View(s) : 1

First, compared with 304 stainless steel, the advantages of duplex stainless steel are as follows: (1) The yield strength is more than twice that of ordinary austenitic stainless steel, and it has sufficient plastic toughness required for forming. The wall thickness of storage tanks or pressure ve...
