Consumables for welding the 9 Ni alloy have been developed. Preheat for 9 Nickel steel. It is well known that welding can seriously alter the metallurgical properties of the material immediately adjacent to the weld joint.
The authors have developed the submerged arc welding method in a vertical upward PF position which is a highly efficient method for welding vertical joints in the 9 Ni steel.
A previous page dedicated to heat resisting alloys includes also a discussion of some. One main type of steel used in the LNG application is nickel steel where steel with 9 nickel stands out due to its good toughness at 196 C. The processes covered are manual shielded metal-arc short-circuiting arc and pulsed spray arc. A common application in which austenitic stainless and 9 nickel steels is in the construction of cryogenic liquefied natural gas LNG containers.
