OTAI Special steel focus on special steel industry above 20 years. Our professional engineer always provide our customer most suitable technique proposal, which will help customer save cost a lot. Especially for the customer who consume big bulk purchase, will save big money for them. We have a customer from Chile, who always import 4140 steel from America. We find their information from their website, try to connect them. At first, it is not smoothly for communication, because their always use material from America, and they do not trust material imported from China. After several months, we get know their application details, our engineer find they can use 4140 steel equivalent 42CrMo instead, that will help them save a lot of cost. Chile customer find our price help them cut more than half cost if our material meet their application requirement. We sent them free samples for test, finally approved by end user. We already work together with this customer above 5 years, regular purchase 4140 steel equivalent 42CrMo from OTAI steel every two months.
If you are purchasing material 42CrMo4, 1.7225, SCM440, 708M40 and EN19, you can contact us for a trail. It is good option for you to consider China standard 42CrMo.
