After heat treatment and cold drawing hardening, 65Mn steel has higher strength, certain toughness and plasticity; under the same surface state and complete hardening, the fatigue limit is equivalent to that of alloy springs. However, due to poor hardenability, it is mainly used for springs of A514 grade B quenched and tempered steel smaller sizes, such as pressure regulating springs, force measuring springs, round and square spiral springs on general machinery or drawn into steel wires as springs on small machinery.
As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's A514 grade B quenched and tempered steel steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole A514 grade B quenched and tempered steel steel transportation industry.
The Indonesia INKA is the only train carriage maker for railway industry in Indonesia. We cooperated with them since 2012 and supply them SPA-H steel. The SPA-H steel is used by them to fabricate train carriage. We have huge stocks for SPA-H steel and can arrange delivery for them in short time after receiving order. Meanwhile, our product A514 grade B quenched and tempered steel quality has passed their test for so many times use. Therefore, they trust us and give us repeat orders regularly. And we also do our best to support them and have never let them down though past cooperations.
We are committed to providing customers with high-quality services, high-precision products and efficient solutions.
