Type 201 stainless steel is an austenitic chromium-nickel-manganese stainless steel, which is developed to save nickel. Type 201 is a low-cost alternative to traditional Cr-Ni stainless steels such as 301 and 304. The nickel is replaced by added manganese and nitrogen. It cannot be hardened by heat treatment, but can reach high tensile strength by cold working. Type 201 is essentially non-magnetic in the annealed condition and becomes magnetic upon cold working. In many applications, the 201 type may replace the 301 type.

A36 is a low-carbon steel containing trace amounts of manganese, phosphorus, sulfur, silicon and other elements such as copper. A36 has good weldability and high yield strength, and is the structural steel plate specified by the engineer. ASTM A36 steel plate is often manufactured into a variety of structural steel parts. This grade is used for welded, bolted or riveted construction of bridges and buildings, as well as for general structural purposes. Due to its yield point, A36 carbon plate can be used to design lighter-weight structures and equipment, and provide good weldability. Construction, energy, heavy equipment, transportation, infrastructure and mining are the industries where A36 panels are commonly used.

The construction industry is mainly used to manufacture anti-corrosion roof panels and roof gratings for industrial and civil buildings; In light industry, it is used to manufacture household appliance shells, civil chimneys, kitchen appliances, etc. In automobile industry, it is mainly used to manufacture corrosion resistant parts of cars, etc; Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, frozen processing tools for meat and aquatic products, etc; It is mainly used for the storage and transportation of materials and packaging tools.

316 stainless steel tubing is a widely used premium grade within the austenitic stainless steel family. Due to the addition of molybdenum (Mo), it offers significant improvements in corrosion resistance, high-temperature stability, and mechanical properties compared to the base 304 stainless steel tubing.

Q345B carbon steel pipe is one of the core pipe materials within the Chinese national standard system (GB/T 1591-2018 ‘Low-Alloy High-Strength Structural Steel’), falling under the category of low-alloy high-strength carbon steel pipes. Owing to its excellent comprehensive mechanical properties and high cost-effectiveness, it finds extensive application across multiple sectors including construction, machinery, chemical engineering, and municipal works.
