  • Product Detail

product description

Stainless steel pipe is a kind of hollow round steel strip, which is widely used in industrial pipelines and mechanical structural parts of petroleum, chemical, medical, food, light industry, machinery and instrumentation. In addition, it is light in weight when the bending and torsional strengths are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures. It can also be used as furniture and kitchenware.

Labeling method

The American Iron and Steel Institute is using three digits to label the various standard grades of malleable stainless steel ground. Among them.

1.austenitic stainless steel with 200 and 300 series of numbers indicated.

2.ferritic and martensitic stainless steel with 400 series of numbers.

For example, some of the more common austenitic stainless steels are marked with 201, 304, 316, and 310, ferritic stainless steels are marked with 430 and 446, martensitic stainless steels are marked with 410, 420, and 440C, duplex (austenitic-ferritic) stainless steels, precipitation hardening stainless steels, and high alloy with less than 50% iron content Usually a patented name or trademark name is used.


Corrosion resistance

International corrosion resistance of materials according to the annual corrosion rate is divided into three categories, the first category for complete corrosion resistance, the corrosion rate is less than 0.1mm / year, high-quality stainless steel belongs to such materials; the second category for still corrosion resistance, the corrosion rate of 0.1-1.0mm / year, belongs to the general stainless steel; the third category for corrosion resistance, the corrosion rate is greater than 1.0mm per year.

Cold rolled description

Cold rolled: Hot rolled coil is used as raw material, and the oxide skin is removed by pickling. The product is rolled coil. The cold work hardening caused by continuous cold deformation makes the strength, hardness and toughness and plasticity of rolled coil increase, so the stamping performance will deteriorate and can only be used for parts with simple deformation. Rolled coil can be used as raw material for hot galvanizing plant because annealing lines are set up in hot galvanizing units. The weight of rolled coil is generally 6-13.5 tons. The hot rolled pickling coil is rolled continuously at room temperature. The inner diameter is 610 mm.

Cold rolled edge

Stretch good, toughness, but the price is more expensive;

Cold rolling processing surface without oxide skin, good quality;

Cold rolling is generally used in the production of strip, the rolling speed is high;

Cold rolling than the thickness of the high precision. Mechanical properties, surface and so on in the hot rolling;

Cold-rolled steel coil due to a certain degree of work hardening, low toughness, but can achieve better yield ratio, used for cold-formed spring and other parts;

Cold coil yield point closer to the tensile strength, so the use of risk in the process of no predictability, when the load exceeds the allowable load prone to accidents

The surface of the cold rolled steel coil without plating is gray.

Cold rolled steel plate surface smoothness is higher than the hot rolled steel coil.
