Annealing Process of Seamless Steel PipeThe workpiece is heated to a temperature between 20 and 40 ° C above the temperature at which the steel begins to form austenite, and is slowly cooled after the heat preservation. During the cooling process, the lamellar cementite in pearlite becomes spherical, thereby reducing the hardness. 3. Isothermal annealing.

Pipe Fittings Manufacturing Process for Elbow, Tee, Cap The pipe end is a flare or spared out to from a flange face. Stub ends are also manufactured by forging in which forge block is machined to final dimension. Fitting Heat Treatment. Hot finished pipe fittings do not require heat treatment, however, for Cold finished pipe fittings Heat treatment is required as per applicable ASTM standard.
Annealing is a heat treatment process used mostly to increase the ductility and reduce the hardness of a material. This change in hardness and ductility is a result of the reduction of dislocations in the crystal structure of the material being annealed. Annealing is often performed after a material has undergone a hardening or cold working process to prevent it from brittle failure or to make it more formable for Cold Rolled Square Pipe Black Annealed For Furniture Black annealed pipe/cold rolled tube for furniture. 1.Specification.
