Stainless steel pipe is a kind of hollow long round steel, which is mainly used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchenware.
Stainless steel is a kind of material with brightness close to mirror surface, tough and cold touch. It is a relatively avant-garde decorative material with excellent corrosion resistance, formability, compatibility and toughness. It is used in heavy
industry and light industry, Daily necessities industry and architectural decoration industries.
1. Stainless steel has different grades, correspond to different hardness, thermoplastic, plasticity and weldability. If you
don't understand, you can tell us your requirements.
2. Stainless steel can be customized for different surfaces, and different surfaces have different applications. For example, 8k mirrors are generally used for decoration.
3. We have more than 30 years of experience in this industry and believe that we can satisfy any demand for stainless steel raw materials.

The stainless steel tube can be classified into a Cr system (400 series), a Cr-Ni system
(300 series), a Cr-Mn-Ni (200 series), and a precipitation hardening system (600 series). 200 series - chrome-nickel-manganese
austenitic stainless steel, 300 series - chrome-nickel austenitic stainless steel.
301-----extension is good for molding products. It can also be hardened by mechanical processing. Good weldability. Wear
resistance and fatigue strength are better than 304 stainless steel.
302-----corrosion resistance is the same as 304, because the carbon content is relatively high and the strength is better.
303-----It is easier to cut than 304 by adding a small amount of sulfur and phosphorus.
304-----that is 18/8 stainless steel. The GB grade is 0Cr18Ni9. 309 - Better temperature resistance than 304.
316-----After 304, the second most widely used steel grade, mainly used in the food industry, the pharmaceutical industry and
surgical equipment, added molybdenum to obtain a special structure resistant to corrosion.
321 - Other properties are similar to 304 except that the addition of titanium reduces the risk of corrosion of the material weld.
400 series - ferritic and martensitic stainless steel.
408-Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409-The cheapest model, usually used as a car exhaust pipe, is a ferritic stainless steel (chrome steel).
410-Martensite (high-strength chrome steel) with good wear resistance and poor corrosion resistance.
416-The addition of sulfur improves the processing properties of the material.
420-"cutting grade" martensitic steel, similar to the earliest stainless steel of Brinell high chromium steel. Also used for
surgical knives, it can be done very brightly.
430 - ferritic stainless steel, for decoration, for example for automotive accessories. Good formability, but poor temperature
resistance and corrosion resistance.
440-High-strength cutting tool steel with slightly higher carbon content. After proper heat treatment, it can obtain higher yield
strength and hardness can reach 58HRC, which is among the hardest stainless steel. The most common application example is the
"razor blade." There are three commonly used models: 440A, 440B, 440C, and 440F (easy processing type).
500 series - heat resistant chrome alloy steel.
600 Series - Martensitic precipitation hardened stainless steel tube.
