Material and corrosion resistance
Stainless steel square steel is made of 200 series, 300 series or 400 series stainless steel, with a chromium content of at least 10.5%. Some models add elements such as nickel and molybdenum to improve corrosion resistance, especially suitable for humid or chemical corrosion environments.
Mechanical properties
Tensile strength ranges from 310-635MPa, and the temperature range can reach -196℃~800℃. Some models (such as 303, 304F) add sulfur to improve machinability, which is suitable for precision parts processing.
Application scenarios
Widely used in machinery manufacturing, petrochemicals, medical equipment, building bridges and rail transportation, etc., replacing traditional welding with modular connection design to improve assembly efficiency and structural stability.

Composition of Stainless Steel
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and
mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
