Product Introduction

EN24 equivalent 40CrNiMo, which is China standard grade, can be AISI 4340, Din 36CrNiMo4, W-Nr 1.6511 equivalent as well. Generally speaking, they can be equivalent each other if not very special application condition.

Most customer purchase 40CrNiMo as EN24 equivalent, especially customer from British, Middle east, and Africa. We sell large quantity to such district big quantity each year. China standard 40CrNiMo are widely accepted as EN24 equivalent and other grade SAE 4340, Din 36CrNiMo4, and W-Nr 1.6511 word wide for reasons as following:
Mechanical Performance for 40CrNiMo and EN24 steel are similar.
Price for 40CrNiMo is much cheaper compared other mentioned grade above
40CrNiMo is the most widely used engineering alloy steel in China, usage is huge, stock is always enough, can support quickly shipment.
China standard steel quality is good, and qualified at almost all condition EN24, SAE 4340, Din 36CrNiMo4, and W-Nr 1.6511 applied.
