Description

Solid wire for Nickel based alloys and dissimilar joints
Suitable for welding and cladding of a wide range of Nickel alloys resistant to high temperature between themselves and with austenitic and ferritic steels. Mn and Nb are added in order to give high resistance to hot cracking and tolerance to dilution by combination with ferrous alloys. Used where good toughness and heat resistance are required and for welding 3% and 5% Ni steels used in plants and tanks for liquid gases. Working temperature from -269°C to 950°C.

Description

Application

These weld metals lack a direct equivalent parent material, but their composition shares similarities with Inconel™ 600. The inclusion of Mn and Nb enhances their resistance to hot cracking, enabling them to withstand dilution by various combinations of nickel-base and ferrous alloys. They maintain consistent properties over a broad service temperature range, spanning from –269°C to temperatures exceeding 900°C. Applications encompass the welding of heat-resisting nickel-base alloys for use in furnace equipment, reaching temperatures up to approximately 900°C.Also employed for mixed welds involving different nickel-base alloys, such as Monel 400, and stainless, low alloy, or C-Mn steels, eliminating the need for preheating. Moreover, they find utility in transition welds between creep-resisting ferritic and austenitic steels, like 2CrMo and 316H, for prolonged service at elevated temperatures in petrochemical and power generation plants. Ideal for cryogenic applications involving 3% or 5% Ni steels in vessels and pipework operating at or below –100°C. Stress relief is optional. Preheat and PWHT depend on the base material, with no preheat needed for most nickel-base materials
