Frequently Asked Questions
What is the difference between B7 and B16 alloy steel washers?
B16 adds vanadium and tempers higher, for better strength above 400°C.
IsAS B16 Round Washer suitable for sour, H2S service?
Standard B16 is not a NACE MR0175 sour-service grade at 35 HRC. Ask about our B7M range for sour duty instead.
Which standard covers Alloy Steel B16 Washer dimensions?
ISO 7089 and DIN 125 cover metric sizes up to M64. Larger sizes follow your drawing.
Do you arrange third-party inspection reports for B16 Alloy Steel Star Washers?
Yes. Third-party inspection reports are available alongside EN 10204 3.1 certificates.
What HSN code applies to Alloy Steel B16 Flat Washer?
Flat and other washers fall under HSN 7318 22. Spring and lock washers fall under 7318 21.
