Stainless Steel Square Bar Description

Stainless Steel Square Bar is a stainless steel bar with a square cross section, usually manufactured by hot rolling or cold drawing. Its main features include:
Corrosion resistance: Due to the presence of elements such as chromium and nickel, stainless steel square bar has strong anti-oxidation and corrosion resistance.
Excellent mechanical properties: It has high strength and hardness and can withstand greater pressure and load.
High surface finish: After fine processing, the surface is smooth and beautiful, suitable for decorative purposes.
Easy to process: It can be cut, welded, bent and other processing technologies, and has strong adaptability.

Stainless Steel Square Bar Technical

According to the stainless steel grade and production process, stainless steel square steel can be divided into many types, the common ones are as follows:
Classification by stainless steel grade:
304 stainless steel square steel: a common type of stainless steel with good corrosion resistance and machinability.
316 stainless steel square steel: with the addition of molybdenum element, it has better corrosion resistance, especially suitable for marine and chemical environments.
201 stainless steel square steel: a more economical type of stainless steel, suitable for general environment use.
430 stainless steel square steel: ferritic stainless steel with good corrosion resistance and heat resistance.
Classification by production process:
Hot-rolled stainless steel square steel: formed by high temperature heating and rolling, with good mechanical properties and dimensional accuracy.
Cold-drawn stainless steel square steel: processed by cold drawing process, with high dimensional accuracy and good surface finish.

Stainless Steel Square Bar Applications

Stainless steel square steel is widely used in the following fields due to its excellent performance and various specifications:
Architecture and decoration: used to manufacture building structures, handrails, guardrails, door and window frames, etc.
Machinery manufacturing: used to manufacture mechanical parts, bearings, tools, etc.
Chemical and food industries: used to manufacture corrosion-resistant equipment, containers, pipes, etc.
Ship and automobile manufacturing: used to manufacture ship and automobile structural parts, decorative parts, etc.

Stainless Steel Square Bar Production Process

The production process of stainless steel square steel mainly includes the following steps:
1. Melting: Melt the stainless steel raw materials at high temperature, remove impurities, and add necessary alloy elements.
2. Casting: Pour the molten stainless steel liquid into the mold and cool it into a stainless steel ingot.
3. Hot rolling or cold drawing: The stainless steel ingot is processed into a square section by hot rolling or cold drawing.
4. Annealing: Eliminate internal stress through annealing and improve the ductility and toughness of the material.
5. Surface treatment: Perform surface polishing, pickling and other treatments to improve surface finish and corrosion resistance.
