OTHER INFORMATION
• Welding of 17/4 plate under 4” thick can be done without preheating, but interpass temperatures up to 300°F are commonly specified.
• With thickness of 17/4 plate exceeding 4”, preheating to 200°F and maintenance of an interpass temperature of 200°F - 500°F is considered necessary in many applications.
• In welding maintain a short arc and keep the heat input low.
• Use stringer beads, avoid wide weaving, avoid stress raisers such as sharp corners, threads, and partial penetration welds.
STANDARD PACKAGING
• TIG 10 lb. tube / 60 lb. carton
• MIG 30 lb. spool
