17-4PH
PH Steel
17Cr-4Ni Martensitic precipitation/age hardening stainless steel offering high strength and hardness along with excellent corrosion resistance.
Hold temperature between 925F
and 1150F for one hour per inch
of
thickness (4 hours Minimum).
Pre-hardened 32 Rc.
Age harden 1150F hardness 33 Rc.

Age harden 925F hardness 43 Rc.
 
308L
Austenitic
S.S.
308L is recommend for use on 304L and 347 grades of stainless steels when service temperatures do not exceed 650F.
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 750F.
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 350F Post-heat 400F.
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.
