Use this article to identify the relevant standard, dimensions and purchasing fields before preparing an RFQ or order.
Hardness Is an Independent Parameter
The same dimensional series can be supplied to different hardness requirements. The reviewed GB/T 96.1/97.1 grade A references list 200HV and 300HV, so standard and nominal size alone may not identify the product.
Carry Hardness Through the Purchasing Process
Keep the hardness consistent across RFQ, order, package marking and incoming inspection. The exact sampling and acceptance rules belong in the agreed quality documentation.
