ASTM A240 304h round bar

Gangsteel produce and export ASTM A240 304H stainless steel plate, ASTM A240 TP304H Stainless Steel No.1 Finish Plate and we supply TP304H stainless steel stock list thickness 2mm to 300mm at Origin China. We are the large stainless material factory supplier in China.

The addition of molybdenum will increase basic corrosion resistance, improves chloride pitting resistance and strengthens the alloy in high temperature service. Through the managed addition of nitrogen it is not uncommon for 316/316L to fulfill the properties of 316 straight grade, whereas maintaining a low carbon content. Type 304L is a variation of Type 304 and has a lower carbon content which improves weldability and lowers the risk of lowered corrosion resistance across the weld. Type 304L also has a barely lower yield and tensile strength than Type 304.

304h stainless steel properties

Such steels are “sensitized” and subject to intergranular corrosion when exposed to aggressive environments. The carbon content of Alloy 304 might enable sensitization to happen from thermal conditions experienced by autogenous welds and heat-affected zones of welds. For this cause, the low carbon Alloy 304L is most well-liked for during which the fabric is put into service in the as-welded situation. Low carbon content material extends the time necessary to precipitate a harmful stage of chromium carbides however doesn’t eliminate the precipitation reaction for material held for long times within the precipitation temperature range.

It resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. However, due to its high carbon content, Alloy 304/304H is topic to carbide precipitation within the heat affected zone of welds.

From a metallographic point of view, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the intruding oxygen from the steel for corrosion resistance.

In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium
SS 304H Plate Equivalent grades









SS 304H



304, 304L, and 304H alloys are the most prone to stress corrosion cracking (SSC) among austenitic stainless steels because of their relatively low nickel content.
The conditions that cause stress corrosion cracking are: (1) the presence of halide ions (usually chloride), (2) residual tension, and (3) the temperature exceeds 120°F (49°C).
Cold deformation during alloy forming, stenting into tube sheet, welding operations, etc. can all cause stress.
Annealing and stress relief heat treatment after cold deformation can reduce stress, thus reducing the possibility of halide stress corrosion cracking.
In the environment that may cause intergranular corrosion, it is best to choose low-carbon 304L alloy when working under low-temperature annealing.

What series of stainless steel is magnetic?

There are several different types of stainless steels. The two main types are austenitic and ferritic, each of which exhibits a different atomic arrangement. Due to this difference, ferritic stainless steels are generally magnetic while austenitic stainless steels usually are not.

Type 347 is stabilized with columbium, it’s preferable for aqueous and low temperature environments as a result of its good resistance to intergranular assault. Both 347 and 321 provide good resistance to polythionic acid stress corrosion cracking, encountered in oil refineries. The excessive temperature oxidation resistance of 347 is just like that of 304 stainless steel.
