Problems of 4140 prehardened plate in China market

First, both good and bad quality are in the market. Some supplier provide 42CrMo materials to replace the American Standard 4140. In fact, the chemical composition of the two materials is different. When foreign buyers receive the goods, the difference can be found by testing the composition. What OTAI provide is the real American Standard 4140.

Second, 4140 Prehardened plate require quenching and tempering process. Some heat treatment plant cannot control the temperature and hardness very well. It lead to the material mechanical properties not meet standard, and eventually there will be various problems in the end use. OTAI 4140 prehardened plate,is completely controlled according to the AISI Standard. All mechanical properties, including tensile strength, yield strength, elongation, shrinkage, impact energy and hardness, are tested and delivered only when they meet the standard completely.

Third, the delivery time is very long, even if the supplier promised a very short delivery time. In fact, they did not have so much inventory, and they had to transfer goods from other stockiest, agent or steel mills. In fact, few stockers can prepare all sizes all the time, and the size of out of stock will greatly extend the delivery time. Therefore, suppliers often say that 7-day delivery, in fact, they may not be able to deliver in one month, consider the long time sea transportation time, oversea buyers have missed the best sales opportunity.

He felt that the information I might tell lie to get his order, and then he worried about the quality and business safety with us.
