The weldability of NM500 steel used for bridges is good. It means that under certain process and construction conditions, NM500 steel used for bridges can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

The wear of NM400 wear plate, NM500 steel used for bridges is a complex phenomenon. Up to now, there is not a simple quantitative law and an exact unified definition of wear. In the glossary of tribological terms compiled by the research group on wear of engineering materials of the organization for economic cooperation and development (OECD), abrasive wear is defined as the wear caused by material transfer due to the action of hard particles or asperities.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
