Top 10 AISI 310S Bar Manufacturers in China 2026

Introduction to AISI 310S Bar

AISI 310S bar is a type of stainless - steel bar. It belongs to the austenitic stainless - steel family. The chemical composition of AISI 310S typically contains around 24 - 26% chromium and 19 - 22% nickel, along with a low carbon content (≤0.08%). This composition gives it excellent high - temperature resistance, oxidation resistance, and corrosion resistance.

AISI 310S bars are widely used in various industries. In the heat - treating industry, they are used in furnace components such as radiant tubes, muffle furnaces, and heat - exchanger tubes because of their ability to withstand high temperatures without significant deformation or oxidation. In the chemical industry, they are used in equipment that handles corrosive substances due to their good corrosion - resistant properties. They are also used in architectural applications where a combination of aesthetic appearance and durability is required.
