321 Stainless Steel Square Bar

321 stainless steel square steel significantly improves its resistance to intergranular corrosion by adding titanium to stabilize carbides, and is especially suitable for high-temperature environments of 450-850℃. Its mechanical properties are equivalent to those of 304, with a tensile strength of ≥515MPa and a yield strength of ≥205MPa. It has excellent oxidation resistance after solution treatment on the surface. It is often used in oil cracking units, heat exchanger tube sheets and other scenes that require both high-temperature strength and corrosion resistance. It can maintain stable performance without annealing after welding. It is a key material in the chemical and energy fields, effectively extending the service life of equipment.

Stainless Steel Square Bar Benefits

1. Strong corrosion resistance: Stainless steel square rods inherit the excellent characteristics of stainless steel materials, have extremely strong corrosion resistance, and can resist the erosion of a variety of chemical substances. This allows it to maintain good performance and stability in a variety of complex environments.

2. Heat resistance and low temperature resistance: Stainless steel square rods can maintain the stability of their physical and chemical properties in high and low temperature environments. For example, the service temperature range of 304 stainless steel square bars can reach -196°C to 800°C, making it suitable for various extreme temperature conditions.

3. Good mechanical properties: Stainless steel square bars have good mechanical properties, such as good hot workability for stamping and bending, and no heat treatment hardening. This makes it easy to shape and process during processing.

4. High aesthetics: After polishing, the stainless steel square rod has a smooth surface and high aesthetics. This makes it widely used in construction, decoration and other fields.

5. Various types: Stainless steel square bars are made of various materials, including 304, 304L, 316L, 310S and other types. Each material has its own unique properties and application areas to meet the needs of different customers.
