NT-312
AWS Specification: ER-312
JIS Specification:

NONE

Other Specification:

FOR STAINLESS STEEL

 

I. APPLICATIONS:

For welding dissimilar steels, high strength and high yield steels.

II. DESCRIPTION:

NT-312 is used for joining and overlaying a variety of metals; carbon steels, spring steels, tool and die steels, and various alloy steels. It is an excellent choice for dissimilar metals and for build-up of high alloy steels. Because of the high ferrite, limit welding to two or three layers only when welding similar cast alloys.

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
