1.4539 (UNS N08904/SUS 890L) is a super austenitic stainless steel engineered for extreme corrosion resistance.

1.4539 (X1NiCrMoCu25-20-5) is a high alloy austenitic stainless steel with good corrosion resistance, stable mechanical properties, and stable corrosion resistance in chloride solutions and high tempe

Alloy 904 stainless steel, also known as 904L stainless steel, is a high alloy austenitic stainless steel that has a wide range of applications in many industries.

Super austenitic stainless steel 904L (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) is a high-alloy austenitic stainless steel with low carbon content, designed for harsh corrosive environments. It is

904L (UNS N08904) is a low carbon super austenitic stainless steel widely used in the chemical processing, oil and gas, and pharmaceutical industries.

904L stainless steel adopts a low-carbon design, and the carbon content is usually controlled at ≤0.02%. This design can effectively prevent the precipitation of carbides during welding and heat treat

In 2025, the price of 321 stainless steel will show the characteristics of "wide fluctuations under cost support", with the main adjustment in the range of 13,000-14,000 yuan/ton in the short term. In

SS316Ti is an upgraded version of 316 stainless steel. It optimizes the intergranular corrosion resistance under welding and high temperature through titanium stabilization, while retaining the excell

SS316 contains molybdenum, so its price is usually about 20%-30% higher than SS321, but its long life can reduce maintenance costs.

SS321 stainless steel is suitable for conventional high-temperature scenarios below 800°C that require resistance to intergranular corrosion, such as food machinery and low-temperature heat exchangers

ASTM A213 TP304 stainless steel pipes are solution treated to ensure uniform austenite structure and are widely used in heat exchange systems in the fields of chemical industry, energy, HVAC, etc.

ASTM A554 is an international standard for welded stainless steel mechanical pipes, covering a variety of stainless steel materials such as austenite, ferrite, martensite, etc. (such as 304/304L, 316/
