Product Description
20G large-diameter seamless steel pipe
20g is a type of steel material, belonging to the category of boiler plates, mainly used for manufacturing high-pressure and higher parameter boiler pipe fittings.
The main components of 20g steel include iron, carbon, manganese, silicon, etc. The carbon content is relatively low, about 0.17% -0.23%, which makes 20g steel have good plasticity and toughness. Manganese and silicon are the main alloying elements with high content, ranging from 1.0% to 1.5% and 0.3% to 0.5% respectively, which endows 20g steel with good strength and corrosion resistance.
In addition, 20g steel also has good mechanical performance indicators such as tensile strength, yield strength, elongation, and impact toughness. The tensile strength is generally between 370-450 MPa, the yield strength is between 240-340 MPa, the elongation is generally between 3% -15%, and the impact toughness is between 40-80 J/cm ². These properties make 20g steel widely used in fields such as petroleum, chemical, power, and construction.
Looking forward to working with you!
