SA516 Grade 70 ZQS700L automotive steel sheet refers to normalized steel products. For steel plates and thin plates with a thickness of less than 40mm, we usually supply rolled steel coils. Plates with a thickness greater than 40mm should be normalized and supplied. The density of ZQS700L automotive steel sheet SA516 70 grade steel plate is 0.284 cu/in3 (7861 kg/m3).

45# steel is commonly used medium carbon quenched and tempered structural steel. The steel ZQS700L automotive steel sheet is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This ZQS700L automotive steel sheet method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate ZQS700L automotive steel sheet EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
