We are a trusted manufacturer of 310 stainless steel bars in China, offering factory-direct pricing, excellent oxidation resistance, and high-temperature strength. Custom options available.
310 stainless steel bar is a high-temperature austenitic stainless steel renowned for its outstanding resistance to oxidation and scaling at temperatures up to 2000°F (1093°C). It is ideal for heat-intensive environments, such as furnace components, heat exchangers, incinerators, and cryogenic structures. The alloy maintains its strength and toughness even at sub-zero temperatures, making it a preferred material in critical industries like power generation, metallurgy, and petrochemical processing.
As a factory-direct supplier, we offer OEM and ODM services, competitive pricing, and quick lead times for global clients. Our 310 stainless bars are produced under strict quality control, supported by full certifications and technical documentation.
