Details Introduction
20g refers to 20# steel, also known as 20g. It is a type of steel material, belonging to the boiler plate category. The "g" in 20g stands for the letter "g" in "boiler" of boiler plate. Besides having the same carbon content, 20g also contains some trace elements suitable for the characteristics of boiler pressure vessels. Additionally, 20g is particularly evaluated for its physical properties, such as bending, impact, and tensile strength.
20g Ingredient:
C——(0.17~0.24)%
Si——(0.17~0.37)%
Mn——(0.35~0.65)%
P——≤0.040%
S —— Seamless square tubes have good quality but higher prices. Welded square tubes are formed by bending and welding sheets, with high temperatures involved during welding that can affect the metal's structure and reduce mechanical stability compared to seamless tubes. Welded square tubes are a type of hollow square section steel tube, also known as hollow cold-formed steel. They are made by cold bending hot-rolled or cold-rolled strip or coil stock into square sections and then high-frequency welded. Besides thicker walls, seamless square tubes also have corner dimensions and edge straightness that meet or exceed those of resistance-welded cold-formed square tubes, with the R angle size typically 2 to 3 times the wall thickness. Custom R angle sizes can also be produced according to customer requirements.
