Stainless SUS304, 304L, SUS316, SUS316L, SUS420J2, SUS440, SUS440C, SUS303, Stainless steel strip

Features

Contains high nickel and is austenitic single phase structure at room temperature, so it has high corrosion resistance compared with Cr13 stainless steel, and has higher plasticity and toughness at low temperature, room temperature and high temperature. And better cold forming and weldability. However, the strength at room temperature is low, the tendency of intergranular corrosion and stress corrosion is greater, and the machinability is poor. Austenite has no phase change when heated, so it cannot be strengthened by heat treatment. It can only be heat treated to improve the corrosion resistance of steel.

Uses

SUS304 stainless steel has been widely used in food, chemical, atomic energy and other industrial equipment and decoration fields, as well as household products, cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical appliances, building materials, chemistry, food industry, agriculture, Ship parts.

SUS316 / SUS316L

Features

SUS316 stainless steel has good plasticity, toughness, cold denaturation, and welding process performance. 316 has good high temperature strength, and 316L has poor high temperature performance, but its corrosion resistance is better than 316. Because of its low carbon content and 2%-3% molybdenum, it is improved It has the corrosion resistance to reducing salts and various inorganic and organic acids, alkalis and salts, and the high temperature strength.

Uses

SUS316 stainless steel is suitable for equipment, chemistry, dyes, papermaking, etc. in seawater.

Features

Stainless steel, corrosion-resistant, no heat treatment, no deformation caused by heat treatment, super mirror processing performance, and good mechanical processing performance in the annealed state.

Uses

For fluorine-containing plastics with corrosive gas or corrosive plastic molds with flame retardant added.

SUS440 / SUS440C

Features

High hardness and good wear resistance. When grinding, its disadvantage is that it is relatively sticky and heats up quickly, but it is easier to grind than any carbon steel, and it is much easier to cut materials by hand. The annealing temperature of 440C is very low, the hardness usually reaches HRC56-58, and the corrosion resistance and toughness are very strong. Now it is more widely used in hand-made knives and high-quality factory-made knives.

Uses

440C has high hardness after quenching, good corrosion resistance (magnetic) tableware (knife), turbine blades after quenching, the hardness is higher than 440 steel (magnetic) blade, nozzle, valve, board ruler, tableware (scissors).

SUS303

Features

Improve cutting performance and high-temperature adhesion resistance. Most suitable for automatic lathes.

Uses

Stainless steel bolts and screws.

Stainless steel strip

Features

It has the advantages of smooth surface, flat surface, high dimensional accuracy, and good mechanical properties. Most of the products are in rolls and can be processed into painted steel plates.

Uses

"Hardness Classification" stainless steel has full soft belt, medium hard belt, extra hard belt, etc. The general hardness is divided into 1/2H, 3/4H, 1/4H, EH, SH. "Optional materials": SUS201, 202, 316L, 316, 304L, 304, 303, 301, 410, 420, 430, 440, etc. "Material Surface": 2B glossy surface, NO1 industrial surface, BA (6K) mirror surface, BA (8K) mirror surface, BA (9K) mirror surface "Use": exhaust pipe, boiler plate, boiler gas bag, mechanical parts, construction Decoration, steel structure manufacturing, solar energy, electronic appliances, metal stamping parts, gaskets, welding pipes, sealing parts, etching parts, computer and mobile phone accessories, etc. "Specifications": thickness 0.01mm-9.0mm, width can be cut into strips.
