The delamination problem of high quality 16mo3 steel

Pageviews:

The strength indexes of high quality 16Mo3 steel pipeline steel mainly include tensile strength and yield strength. At the same time, the yield strength ratio (yield strength to tensile strength ratio) of pipeline steel is also required, which is generally in the range of 0.85-0.93. Pipeline steel shall have enough high impact toughness (crack initiation and crack arrest toughness). For the base metal, when the toughness of the high quality 16mo3 steel material meets the requirements of crack arrest, its toughness generally can also meet the requirements of crack prevention.

Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the high quality 16mo3 steel hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the high quality 16mo3 steel steel industry.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the high quality 16mo3 steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between high quality 16mo3 steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, high quality 16mo3 steel.

The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel high quality 16mo3 steel plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
