What is 321H Stainless Steel Clad Sheet?
321H stainless steel clad plate is a composite material formed by titanium stabilized high carbon austenitic stainless steel and carbon steel substrate through explosive cladding or rolling cladding process. This material combines the high temperature strength and excellent intergranular corrosion resistance of 321H stainless steel with the high strength and economy of carbon steel, and is widely used in petrochemical, pressure vessels, boilers, high temperature heat exchangers and other equipment.

Advantages of 321H Stainless Steel Rolling Sheet
What is the core difference between 321H and ordinary 321 stainless steel composite plates?
321H is a medium carbon type (C=0.04-0.10%), and ordinary 321 is a low carbon type (C≤0.08%). The high temperature creep strength of 321H is increased by 10%, which is suitable for high temperature scenes with long-term load (such as high-pressure steam pipelines).
Application of 321H stainless steel plate
Petroleum refining equipment (reaction tower, distillation tower lining)
High temperature pressure vessels and heat exchangers
Chemical anti-corrosion lining
Power station boiler high temperature pipeline
Does 321H stainless steel composite plate need heat treatment after welding?
General situation: No heat treatment is required, and the titanium stabilization design has ensured the HAZ's resistance to intergranular corrosion.
