S275JR channel steel refers to a specific type of channel steel made from S275JR steel. S275JR is a commonly used non-alloy structural steel grade. It has a minimum yield strength of 275 MPa and a tensile strength of 410-560 MPa, depending on the thicknes
Ferro silicon is an alloy of silicon and iron. Silicon acts as a strong steel oxidant. Used primarily in special steels and in small quantities in mild steel.
The termination temperature of hot rolling is generally 800 ~ 900 °C, after which it is cooled in air, thus the hot rolling state is equivalent to normalizing.Most steel is rolled by hot rolling. Hot-rolled steel, due to the high temperature, the surface
Titanium frit is mainly used for impermeable bottom glaze of ceramic inner wall tile, bottom glaze and surface glaze of exterior wall tile and floor tile.
Electro-galvanized is obtained by applying a power source and obtaining a plating layer by electrodeposition. The obtained plating layer is composed of fine pure zinc grains.
The black tube is made from hot rolled steel strip, so the application scope of the tube is greatly expanded. It is mainly used for construction, machinery manufacturing, shipbuilding, steel construction projects, solar power support, steel structure engi
Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most ch
