Features

Good corrosion resistance: 300 series stainless steel has good corrosion resistance at room temperature, and can resist the erosion of most organic acids, inorganic acids and salts and other media.

Excellent processing performance: 300 series stainless steel has good plasticity and weldability, which is convenient for various processing applications, such as stamping, bending, welding and so on.

Good mechanical properties: 300 series stainless steel can still maintain high strength and hardness at high temperatures, suitable for high strength requirements of the working environment.

Beautiful and durable: 300 series stainless steel has good gloss and decorative properties, which can meet the occasions with high requirements for product appearance, and also has a long service life.

Classification

300 series stainless steel can be divided into a variety of different types according to its specific composition and characteristics, common 304, 316, 321 and so on.

SUS304: Contains 18% chromium and 8% nickel. It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, stamping and bending. Good hot workability, no heat treatment hardening phenomenon, non-magnetic. Widely used in household goods (1, 2 types of tableware), cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical equipment, building materials, chemicals, food industry, agriculture, ship parts.

SUS304L: austenitic basic steel, the most widely used; Excellent corrosion resistance and heat resistance; Good low temperature strength and mechanical properties; Single-phase austenitic structure, no heat treatment hardening phenomenon (non-magnetic, use temperature -196--800℃).

SUS304Cu: Austenitic stainless steel with 17Cr-7Ni-2Cu as the basic composition; Excellent formability, especially good wire drawing and aging crack resistance; Same corrosion resistance as 304.

316 stainless steel: contains 16-18% chromium and 10-14% nickel, added 2-3% molybdenum, has better corrosion resistance, suitable for Marine environment and chemical industry and other fields.

321 stainless steel: containing 17% chromium and 9-12% nickel, adding 5% titanium, has excellent high temperature resistance, often used in high temperature stoves and heat exchange equipment and other occasions.

Applications

300 series stainless steel has been widely used in many fields due to its excellent properties.

Construction field: 300 series stainless steel is often used in indoor and outdoor decorative materials, handrails, stairs, doors and Windows, etc., and its beautiful appearance and weather resistance have won wide praise.

Chemical industry: Due to the strong resistance of 300 series stainless steel to corrosive media such as acid and alkali, it is often used in chemical containers, pipelines, valves and other equipment.

Food processing field: 300 series stainless steel meets the hygiene requirements, will not pollute food, widely used in food processing equipment, kitchenware and so on.

Marine and Marine engineering: 316 stainless steel has good seawater corrosion resistance and is often used in ship components, offshore platforms and so on.

Medical devices: 300 series stainless steel has good biocompatibility and is widely used in the manufacture of medical devices and medical equipment.
