304/304L/304H Stainless Steel Grade:
For maximum corrosion resistance, the material should be annealed at 1900°F (1038°C) minimum and water quenched or rapidly cooled by other means after hot working.
304/304L/304H Stainless Steel Grade:
It is quite ductile and forms easily. Cold working operations will increase the strength and hardness of the alloy and might leave it slightly magnetic.
304/304L/304H Stainless Steel Grade::
It can be readily welded by most standard processes.

What Is The Difference Between 304, 304L And 304H?
Answer:
304 is considered the most versatile and widely used austenitic stainless steel, 304L is the ultra low carbon variant of 304 stainless, while 304H is the high carbon version of the 304 stainless. Carbon content is the only chemical difference between these three grades, leading 304L to perform better in corrosive environments and be easier to weld.
Why Is 304L Easier To Weld Than 304?
Answer:
The lower carbon content in 304L helps to remove the chromium carbide precipitation that occurs during the welding, putting 304L at lower risk for intergranular corrosion even in highly corrosive environments.
What Is The Yield Strength Of This Grade Stainless Steel?
Answer:
The yield strength for 304 stainless is 205 MPa (30 ksi).
