Shielding gas for TIG welding

Shielding gas is one of the key parameters in the TIG welding process. We know that the shielding gas is mainly Ar and CO2 used in TIG welding, in many applications, O2, H₂, He or N₂ can be added to improve the welding quality. In addition to argon, helium or a mixture of argon and helium can be used […]

How to weld TP310HCbN(HR3C) steel?

Stainless steel grade TP310HCbN also referred as HR3Csteel, has much higher strength than conventional 310 stainless steels utilizing finely dispersed M23C6 and NbCrN, the 25Cr-20Ni chemical composition offer much better steam oxidation resistance than 18Cr-8Ni Austenitic stainless steels. TP310HCbN Austenitic heat resistant steel is widely used in superheater and reheater systems with an operating temperatures higher than […]
