GETIG 318Si

IDENTIFICATION : ER 318/ER 318Si

CLASSIFICATION : AWS/SFA 5.9 ER 318/ER 318Si BS 2901- 90 318 S 97 DIN 8556 SGX5CrNiMoNb 19 12

DESCRIPTION :

Getig 318Si is designed for welding the Nb or Ti stabilized 18 Cr/12%Ni/2.5%Mo austenitic stainless steel grade 316Cb and 316 Ti. It is primarily intended for use at service temperatures above 400°C. Resistant to inter-granular corrosion up to 400°C. It is suitable for welding of corrosion resistant CrNi(Mo) alloys steels in different devices, vessels and parts in chemical, cellulose, temperature 400° C.
