Delivery status of S700MC steel plate: The steel plate is delivered in a hot-rolled state, if there are other requirements. stated in the warranty.

S700MC steel plate is prone to cracking in the use of coiled plates. It can be optimized by optimizing the coiling temperature, adjusting the disc gap, and grinding the main thorns. And the S700MC steel plate has good feedback during use, without any shearing and bending phenomenon.

With the development of construction machinery in the direction of large-scale, light-weight and heavy-load equipment, the proportion of high-strength steel used and the quality requirements have been greatly improved. The research and development and production of high-strength construction machinery steel in China have made rapid progress. The quality and strength requirements of high-strength steel are getting higher and higher. S700MC steel plate is a low-carbon microalloyed cold forming steel. It adopts niobium and titanium microalloying and controlled rolling air cooling technology, and is widely used in construction machinery and vehicle structures.
