Heat treatment is very important for the quality of forging bolts and nuts. Smart Engineering and Fasteners are capable to perform heat treatment depending on the client’s requirements and standards. Our entire hot forging facilities are furnished with adequate heat treatment facilities. At SEF all heat treatment furnaces are calibrated and certified on regular basis to international standards
Heat treatment is an industrial and metalworking procedure. The heat treatment procedure employs cooling and heating operations to the metals or alloys in the solid-state of matter. Fasteners are subjected to heat application to achieve desired modification in rigidity, malleability, material strength, and smoothness. SEF performs types of heat treatments including quenching, tempering ,age hardening and normalizing on products which SEF manufactures.
General:
Metallic items consist of a microstructure of small crystals. The nature of these crystals or grains is the most effective factor. The temperature for heating metals and the rate of cooling after heat treatment can alter the properties of metal. The most common reason for which metal requires heat treatment is to improve the strength, toughness, hardness, and corrosion resistance.
Our heat treatment facilities comprise:
Heat treatment of fasteners is a critical part of the manufacturing process. The control of atmosphere, time, and temperature determines the quality, reliability, and capability of the fastener. Fastener’s finished characteristics need to comply with the target strength range because if material properties are not correct after heat treatment, the fastener may fail in its application. Our all facilities are equipped with state-of-the-art metallographic and microscopic material inspects necessities to ensure the quality of heat treatment procedure.
Heat treatment of steel bolts is employed to dissolve coarse chromium carbide particles that may reduce corrosion resistance and toughness. The carbide solution treatment of stainless-steel fasteners can improve cryogenic or low-temperature toughness. Usually, high-strength bolts have a hexagonal head with marking indicating the strength level of heat treatment. The material strength is indicated by the grade
Our manufacturing premises have inspection facilities for the following:
Additional tastings are performed in BS EN ISO/IEC17025 certified accredited laboratories to ensure compliance and end results after the process.
