304/304L/304H stainless steel plate is one of the most widely used austenitic stainless steel grades. The grades shows high strength, excellent corrosion resistance and outstanding formability than any other grade of stainless steel. It is frequently utilized in oil and gas industries etc..
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.

Hot rolling is a metalworking process. Such as steel ingots or billets are difficult to deform and process at room temperature, they are generally heated to 1100 to 1250° for rolling, this rolling process is called hot rolling. Most steel materials are rolled by hot rolling, the steel delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can bestored in the open air. In addition, hot rolling is that it can destroy the casting structure of the ingot, refine the grain of the steel, eliminate structural defects, make the steel structure dense, and improve the hardness of the hot rolled steel.
Cold rolling refers to a rolling process that uses the pressure of rolls to squeeze steel to change the shape of the steel at room temperature. The advantafe of cold rolling is fast forming speed, high output, the coating is not damaged, and it can be made into a variety of cross-sectional forms to meet the needs of the use conditions. In addition, cold rolling can cause large plastic deformation of the steel, thereby increasing the yield point of the steel. Which is Widely used in home appliances and other industries.
According to the forging temperature, forging can be classified into hot forging, cold forging and warm forging. Hot forging is the most widely used forging process. In hot forging process, the recrystallization accompanying the high temperatures and enhanced formability enables a precise adjustment of very fine-grained microstructure. Strength-durability combinations can be specified more so than in any other forming process. Which is predominantly used for aerospace industry.
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).
