Effect of heat treatment process on impact properties of S460M VS S460ML

With the development of remote oil and gas fields, polar oil and gas fields, offshore oil and gas fields and acid oil and gas fields, oil and gas pipeline engineering is facing challenges of high-pressure transmission and harsh environment such as low temperature, large displacement, deep sea and acid medium. In order to ensure the enthusiasm and safety of pipeline construction and operation, the basic requirements and development trend of S460M VS S460ML, pipeline steel are high strength, high toughness, large deformation, thick wall, high corrosion and good weldability.

20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.

During the welding of hardfacing wear-resistant steel plate, S460M VS S460ML, the welding shall be carried out in strict accordance with the drawing, welding process and relevant standards. Follow the welding sequence of first welding the base layer, then welding the transition layer, and then welding the multiple layer. In order to prevent adhesion of welding spatter, anti spatter coating should be applied within 100 mm on both sides of groove of stainless steel clad plate before welding.

The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate S460M VS S460ML after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our S460M VS S460ML steel mill.

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.
