Stainless steel pipes have excellent properties such as strength, high wear resistance, superior corrosion resistance and not easy to rust. They are widely used in industries, food machinery, electrom

Stainless steel polishing tubes mainly include three methods: mechanical polishing, chemical polishing and electrolytic polishing.

316 sanitary stainless steel pipes are widely used in the manufacturing process of medical drugs. Due to its safety, hygiene, environmental protection, durability and non-toxicity, it can meet the hig

Stainless steel polished pipe is a kind of pipe with good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot processing properties such as stamping and

The dimensional tolerance and form and position tolerance of sanitary stainless steel pipes are higher to ensure the sealing and stability of the connection; the tolerance accuracy of industrial pipes

316L stainless steel pipes are usually more expensive than 304 stainless steel, about 20%-30% more expensive.

304 stainless steel water pipes have good corrosion resistance and are suitable for general water use environments.316L stainless steel water pipes can cope with more complex environments, such as hig

The polishing treatment of 420 stainless steel mirror tube is a process of fine grinding and polishing the stainless steel surface by mechanical or chemical means to obtain a high-gloss mirror effect.

420 stainless steel has higher hardness and wear resistance, but slightly poorer toughness; 416 stainless steel has good processing performance and toughness, but is relatively weak.

AIS1 440 stainless steel is a high carbon, high gluten martensitic stainless steel, including three grades: 440A, 440B and 440C. These steels are known for their high strength, good hardness, corrosio

20Cr13 and 30Cr13 stainless steel are both high-quality martensitic stainless steel materials, suitable for making knives.

SUS 420J1 and SUS420J2 are both martensitic stainless steels. The former has a carbon content of about 0.15%, a lower hardness (≤223HB) and better toughness, making it suitable for ordinary wear-resis
