308L Austenitic S.S. |
308L is recommend for use on 304L and 347 grades of stainless steels when service temperatures do not exceed 650°F. |
No pre-heat is recommended. Cool deposit as quickly as practical. |
|
312 Special S.S. |
312 has superior mechanical properties when compared to other 300 series stainless steels. Recommended to join dissimilar alloys and as a build up for harder alloys. |
Pre and post heat according to base metal chemistry. |
|
316L Austenitic S.S. |
316L can be used on all 300 grades of stainless steels. Recommended for use on grades 304, 316, 316L and 318. | No pre-heat is recommended. Cool deposit as quickly as practical. |
|
347 Austenitic S.S. |
347 is recommended for use on 347 and 321 grades of stainless steels. Especially recommended where weld metal is to be subjected to temperatures above 750°F. |
Pre and post heat according to base metal chemistry. |
|
411 410 Modified |
411 is a 410 mod alloy recommended for use on 405 and 410 grades of stainless steels. Higher nickel and molybdenum content than 410 stainless steel improves corrosion resistance at elevated
temperatures. |
Pre and post heat according to base metal chemistry. |
|
As welded hardness: 34-38 Rc. |
|||
420 Martensitic S.S. |
420 stainless steel is a hardenable 12% chrome steel with higher strength and hardness and better wear resistance than 410 stainless steel. |
Pre-heat 350°F
Post-heat 400°F. |
|
As welded hardness: 48-51Rc. |
|||
502 Chrome Molly |
Recommended for use on types 501 and 502 stainless steels. Good resistance to corrosion and oxidation at elevated temperatures. |
Pre and post heat according to base metal chemistry. |
|
505 Chrome Molly |
Recommended for use on 505 grade stainless steel. |
Pre and post heat according to base metal chemistry. |
