Heat remedy is a seamless steel pipe thermal processing technology that heats, seamless steel tube heats, and cools seamless steel pipe in a certain medium, and controls its efficiency by altering the surface or internal crystalline structure of the material.
In addition to annealing and tempering, there are three varieties of regular heat remedy processes:
Normalization
Normalization processing, additionally known as normalization processing. The normalizing remedy in the heat remedy technique of seamless steel pipes is definitely normalizing therapy. If you liked this article and you would like to be given more info about seamless steel tube price nicely visit the webpage. Usually in the recent working process, the construction of the seamless steel pipe material modifications, and the performance also adjustments accordingly. In order to restore the structure to normal, normalizing treatment is commonly used, so normalizing therapy is also referred to as normalization therapy.
Normalization remedy can be utilized as a closing heat treatment, or seamless steel tube price as a pre-heat remedy, and may enhance processing performance. Normally, carbon steel normalizing remedy is a heat therapy process that heats a carbon steel workpiece that has been heated to a high temperature and completes austenitization, and is immediately cooled within the air to acquire a effective pearlite structure. The structure of normalizing heat treatment has better complete mechanical properties.
Quenching
Quenching is to heat the seamless steel pipe to a temperature above the austenitizing temperature, specifically the critical temperature AC3 (hypoeutectoid steel) or AC1 (hypereutectoid steel), and hold it for a time frame to make it absolutely or partially austenitized Then, the heat remedy strategy of martensite (or bainite) transformation is performed by cooling sooner than the crucial cooling fee to under Ms (or near isothermal temperature).
In addition, the strong solution treatment of aluminum alloy, copper alloy, titanium alloy, tempered glass and different materials or the heat therapy course of with rapid cooling course of is often called quenching.
Tempering
Quenching and tempering is a double heat remedy of quenching and excessive temperature tempering. Quenching and tempering can modify the efficiency and materials of seamless steel pipe to a large extent, and its strength, plasticity and toughness are good, and it has good complete mechanical properties.
During quenching and tempering, the quenched a part of the seamless steel pipe obtains a microstructure dominated by high-quality needle-shaped quenched martensite. However, high-temperature tempering refers to tempering between 500-650, and tempered sorbite is obtained after high-temperature tempering. This is a mixture of ferrite and granular carbide.
Tips: ASTM A106 Seamless Pipe is usually used in the construction of oil and gasoline refineries, energy plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit greater temperatures and strain levels.
