Stainless Steel Alloy 304-H

Type 304-H is a T-300 series, low-carbon austenitic stainless steel alloy. Type 304-H is the most common grade of stainless steel; you may know it as the classic 18/8 stainless steel or A2. Because of its popularity, the versatile and widely used Type 304-H is found in the manufacturing of:

• Shafts
• Valve bodies
• Valve trim
• Pans and cooking tools for the food industry
• Boilers
• Pipelines
• Heat Exchangers
• Cooling towers
• Steam exhausts
• Electric generation plants
• Condensers

Type 304-H retains its popularity because of its unique properties which include:

• Good oxidation resistance in continuous service to 920O C
• High tensile yield strength
• Short and long-term creep strength
• Resistance to corrosion from oxidation and organic acids

To be considered Type 304-H stainless steel, an alloy must contain a specific combination of chemical properties. These include:

• Cr 18-20%
• Ni 8-10.5%
• C 0.04%-0.10%
• Si 0.75 max
• Mn 2% max
• P 0.45% max
• N 0.10% max

Type 304-H stainless steel is available from Yuze Metal in plate, round bar, flat bar, tube, and more. All of our Type 304-H stainless steel meets ASTM, ASMW, EN, and DIN standards.
