What is Grade A105 Elbow ?
Grade A105 is primarily made from carbon steel material grades and they are used to make strong forged fittings.ASTM A105 carbon steel socket weld elbows are the same as their base metal but have 2-2.5% additional nickel to ensure a 50/50 weld balance that retains the weld metal.
It has good resistance in chloride filled environments. It has a high resistance to corrosion， making it very popular in different industries such as petroleum， chemical， oil and gas.
