material SM490YB top manufacturer in Malaysia
The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable material SM490YB steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.
As the thickness and hardness of material SM490YB increase, the tendency to crack at the cutting edge increases. In order to prevent the material SM490YB from cutting cracks, preheating should be carried out before material SM490YB cutting. Special attention should be paid to preheating to make the entire material SM490YB interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole material SM490YB cannot be preheated, the partial preheating method can be used instead.
