Grade ER307Si Wire is an austenitic stainless steel with very little or no ferrite content. The high content of silicon in the SS ER307Si guarantees a smooth spatter-free weld deposit. Stainless Steel ER307Si Filler Wire is an outstanding welding wire for applications that require dissimilar joints, buffer layers and difficult-welding steels. ER307Si SS Filler Wire has high durability and cracking resistance in a wide range of situations, including welding in mild, low alloy, armor, hardening and stainless steel.
ER307Si Stainless Steel Welding Wire has good properties over service temperatures ranging from -50 degrees C up to ~500 degrees C, with good scaling resistance up to ~850 degrees C. Stainless Steel ER307Si Welding Wire may also be subjected to PWHT without any loss of toughness or ductility. ER307Si SS Filler Wire is an excellent choice for welding dissimilar metals such as carbon steel to stainless steel requiring PWHT. The resulting weld deposit has a corrosion resistance of up to 1560 degrees F.
SS ER307Si Filler Wire is also used for surface finishing and repair of 13 percent Mn 'Hadfield' steels. ER307Si SS Welding Wire can work-harden to ~400HV offering a versatile surfacing wire and welding metal for the joining of wear-resistant steel. SS ER307Si Wires are very versatile wires for fabrication, repair and maintenance applications.
