2Cr13 Stainless Steel Composition & Martensitic Strength Properties

2Cr13 is a martensitic stainless steel specified in GB/T 4237 and GB/T 4238. Containing approximately 12–14% chromium with a carbon range of 0.16–0.25%, it offers good heat-treating capability and a balanced combination of corrosion resistance and mechanical strength.

After quenching and tempering, the grade achieves enhanced strength and toughness while maintaining moderate corrosion resistance. It is commonly used in turbine blades, valve components, pump shafts, and structural mechanical parts.

2Cr13 is available as plates, bars, forgings, and tubes. It is widely used in power generation equipment, machinery manufacturing, and petrochemical installations.
