ELECTRODE 312L S/S WELDALL 3.2MM

Hyundai S-312.16 Weld All Electrodes
S-312.16 is a lime-titania type electrode, has an excellent usability and weldability. Chemical composition of all-weld metal is 29%Cr-9%Ni. Owing to the austenite structure containing large contents of ferrite, S-312.16 has good crack resistability. Excellent buffer effect against outer stress.

Characteristics on usage
Bond welding of dissimilar metals such as stainless steel, carbon steel and low alloy steel. Welding of stainless steel clad. Under laying of the build-up welding of high alloyed tool steel and hardfacing.

Notes on usage

• Preheat the base metal at over 200°C (392°F) to prevent cracking in welding of high alloyed steel, having good harden-ability such as tool steel.
• Keep the current as low as possible and length as short as possible.
• Dry the electrodes at 350°C (662°F) for 60 minutes before use.
