Welding wire ER 316LSi is intended for deposit welding and for welding of essential constructional blocks that are composed of various steels. It is primarily subjected to welding of carbon steels with engineering stamped hardly-weldable (alloyed) steels. Wire is also used for manual arc welding of equipment made of chrome-nickel or chrome-nickel-molybdenum steels that operate in corrosive environments at a temperature of 350 °C and which are not exposed to heat treatment after welding. It is also utilized for deposit welding on edges of products perlitic steels. Such wire is applied for welding of essential parts of gas and steam turbines made out of heat-resistant austenitic forged cast steels: X6CrNiMoNb17−12−2, X12CrNi23−13, AISI 316 and similar grades that operate at a temperature of 550−600°С. It is also applied to remedy the casted defects of this steel grades.

Welding wire of ER 316LSi grade is utilized when welding the critical equipment composed of steel of chrome-nickel-molybdenum grades: X10CrNiMoTi18−12, X2CrNiMoN225, X6CrNiMoTi17−12−2 and identical to them grades. It is used in cases when there are severe requirements of metallic seam such as corrosion resistance. This wire is also used for quick-wear parts of machines and for deposit welding of hot and cold cut dies. There are made the following electrodes out of this steel grade: OK 63.35/Jungo 316L, Е19.123МэВ22 (E 318−15), OK 68.53, OK 63.30, OK 63.85, ОК 48.00, E 316−15.
