SUS316H High- Carbon Stainless Steel

Description

SUS316H is the high-carbon version of SUS316, engineered for enhanced high-temperature strength and creep resistance. With a carbon content of 0.04–0.10%, it delivers superior mechanical performance at elevated temperatures compared to SUS316 and SUS316L. It maintains the excellent molybdenum-based corrosion resistance of the 316 series, making it ideal for high-temperature and mildly corrosive environments. It is commonly used in power plants, petrochemical facilities, and industrial heating systems.

Chemical Composition

C 0.04–0.10, Cr 16.0–18.5, Ni 10.0–14.0, Mo 2.0–3.0, Mn ≤ 2.00, Si ≤ 1.00, P ≤ 0.045, S ≤ 0.030

Mechanical Properties

Tensile Strength ≥ 520 MPaYield Strength ≥ 205 MPaElongation ≥ 40%Hardness ≤ 215 HB

Advantages

Higher high-temperature creep strength than SUS316 and SUS316L; good oxidation and corrosion resistance; suitable for high-temperature pressure parts.

Applications

High-temperature piping, boilers, heat exchangers, petrochemical pressure vessels, and furnace components.

Equivalent Grades

AISI 316H, UNS S31609, EN 1.4406, GB 07Cr17Ni12Mo2
