aIt is the intent of this specification to provide ductile nickel alloy weld deposits on materials such as carbon steel, low alloy steels, martensitic stainless steels, Cr-Mo steels, austenitic stainless steels and nickel base alloys in cases where PWHT is not practicable (e.g., due to concern...
PURPOSE: To improve the delayed fracture properties, particularly, as for the spot weld zone in steel rod while the relaxation properties and mechanical properties similar to those of the conventional one are maintained as for the base metal. ;CONSTITUTION: This PC steel rod is constituted of a...
The weld deposit consists of at least two layers of different filler material, where after cooling, the filler in one layer forms a structure with a larger vol. than the filler in the other layer. The deposit pref. consists of alternate layers of a steel forming martensite, and a steel ...
PROBLEM TO BE SOLVED: To provide a steel member and a structure which have strength satisfying API (American Pipe Institute) standards 5L-X65 or higher, and in which critical CTOD (Crack Tip Opening Displacement) at -10°C is ≥0.20 mm in both of a weld metal and a weld line in the...
PROBLEM TO BE SOLVED: To provide a ferritic stainless steel sheet in which sufficient corrosion resistance can be secured even regarding dissimilar welds with an austenitic stainless steel (e.g., SUS304).岡田 修二船川 義正宇城 工太田 裕樹...
Being the ferritic stainless steel weld metal where it matches penetration formPROBLEM TO BE SOLVED: To provide a ferritic stainless steel weld metal which is excellent in penetration shape and formability and capable to be formed into complicated profiles.矢埜 浩史...
with the spiral weld in the pipe; and >=1 second groove at 90 degrees to the first groove. The steel pipe is aligned on a conveyor feeding the pipe stepwise over the head. Several spiral grooves are pref. provided on the segments, and the steel pipe can pref. be rotated by the ...
The present invention provides a lean duplex stainless steel able to suppress the drop in corrosion resistance and toughness of a weld heat affected zone and is characterized by containing, by mass%,C: 0.06% or less, Si: 0.1 to 1.5%, Mn: 2.0 to 4.0%, P: 0.05% or less, S: 0.005% ...
