What is 304H Stainless Steel :
Stainless Steel 304H is a deformed product of 304 austenitic alloy with 18% chromium and 8% nickel. The carbon content of this product is controlled within 0.04-0.10, which improves the high temperature resistance of the product components in a temperature environment higher than 800°F. This alloy has a wide range of uses, with strong corrosion resistance and easy assembly.

304H Stainless Steel Processing - Cold Forming:
The alloy is very ductile and can be easily formed
Helps increase the strength and hardness of the alloy
May make the alloy slightly magnetic
304H Stainless Steel Machinability:
Work hardening occurs during deformation
304H Stainless Steel Chip breaking:
Best results with slower speeds, heavier feeds, good lubrication and sharp tools.
304H Stainless Steel Most commonly used in: Refineries, Boiler, Heat exchanger, Condenser, Pipeline, Cooling Tower, Steam emissions, Power plant, Fertilizer plants, Chemical plants.
