ASTM A312 304L 316L 6mtr Seamless Stainless Steel Pipes Grey White Surface Annealed Pickled

Stainless steel pipe is a hollow, long piece of corrosion-resistant alloy steel. Its core component is iron, containing at least 10.5% chromium (Cr). Elements such as nickel (Ni) and molybdenum (Mo) are often added to enhance specific properties. Its most prominent features are its exceptional corrosion and oxidation resistance, thanks to the dense passive film formed on its surface, which enables its widespread use in humid, chemically corrosive, or high-temperature environments. Stainless steel pipe also offers excellent strength, toughness, sanitation (easy to clean and disinfect), and good machinability and weldability. Common materials include austenitic stainless steels such as 304 (general-purpose) and 316 (more corrosion-resistant, containing molybdenum). Its applications are extremely diverse, encompassing architectural decoration (handrails, guardrails), fluid transportation (water, gas, chemical media), food and beverage processing, medical devices, automotive manufacturing, energy industries (petroleum, nuclear power), household goods, and precision instruments. It is an indispensable key material in modern industry and life. Surface treatments such as polishing and sandblasting can be applied to meet aesthetic and functional requirements. Overall, stainless steel pipes are the preferred pipe material in many areas due to their durability, hygiene, aesthetics, and versatility.

Acid-Resistant Pressure Resistance 316 304 Seamless 201 Stainless Welded Cold Rolled Stainless Steel Pipe

Stainless steel pipe is a hollow long round steel material, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural parts. In addition, when the bending and torsional strengths 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 in furniture and kitchen utensils.

High Quality ASTM Heat Resistant Seamless Steel Pipe 431 631 Stainless Steel Tube

Stainless steel pipes are made of stainless steel with a chromium content ≥10.5% (such as mainstream grades 304 and 316L). They have high strength (tensile strength ≥515MPa), excellent corrosion resistance (surface passivation film is resistant to acid/salt corrosion) and hygienic safety (food-grade surface finish Ra≤0.8μm). They are manufactured through seamless cold rolling or high-frequency welding pipe processes and are widely used in chemical pipelines (acid-resistant 316L), building structures (304 curtain wall keels), medical equipment (precision sterile pipes) and energy equipment (LNG ultra-low temperature transmission pipes). They are the core basic materials in the field of high-end manufacturing.

The Rockwell hardness test of stainless steel pipe is the same as the Brinell hardness test, which is an indentation test method. The difference is that it measures the depth of the indentation. Rockwell hardness test is a widely used method at present, and HRC is second only to Brinell hardness HB in steel pipe standards. Rockwell hardness can be applied to the determination of very soft to very hard metal materials, it makes up for the Brinell method is not, is simpler than the Brinell method, can directly read the hardness value from the dial of the hardness machine. However, due to the small indentation, the hardness value is not as accurate as the Brinell method.
