Heat Treatment Process of AISI WERKSTOFF NR. 1.7218 Tab Washers
Standard Heat Treatment Cycle
Austenitizing
Heated to 870–900°C to convert structure to austenite
Oil / Water Quench
Rapid cooling in oil (thin sections) or water (heavier sections)
Tempering
Re-heated to 400–565°C to balance strength and toughness
Stress Relieving
650–675°C soak removes forming & machining stresses
Hardness Verification
Every lot spot-checked on Brinell & Rockwell scale before packing
Testing Methods of AISI UNS G41300 Split Washer
PMI Testing
Positive Material Identification on every heat
Hardness Testing
Brinell & Rockwell check against ordered condition
Dimensional & Visual
OD, ID, thickness & surface checked per lot
Installation Process of ASTM A322 Machine Washer
Match Washer ID To Bolt Size
Confirm washer inner diameter fits the stud or capscrew
Step 1
Clean The Mating Surface
Remove scale, paint or rust from the joint face
Step 2

Frequently Asked Questions
Is an AISI 4130 Washer magnetic?
Yes, AISI 4130 is a ferromagnetic chrome-moly alloy steel, unlike austenitic stainless washers.
What is the difference between AISI 4130 and AISI 4140?
4130 carries lower carbon than 4140, giving it easier weldability at a small trade-off in through-thickness strength.
Can AISI UNS G41300 Tooth Washer be used in H2S service?
Yes, when hardness is controlled to NACE MR0175 limits during heat treatment and testing.
Do AISI 4130 AISI Slot Washer need heat treatment before use?
Most orders ship normalized; hardened & tempered condition is available where higher strength is required.
