JIS G3461 STB510 Heat Resistant Carbon Steel Pipe are mainly used in boilers, heat exchangers and similar high-temperature equipment.

ASTM A179 / ASME SA179 tubes are seamless cold-drawn low-carbon steel tubes used in heat exchangers, condensers and similar heat-transfer service. This article summarises the chemi

There are many ways to heat treat. So what is heat treatment and when should it be done?

Normalizing heats steel 30-50 C above its upper critical temperature and cools it in air, producing a fine, uniform pearlitic structure. It refines grain, relieves stress and impro

Annealing below the critical temperature AC1 - process annealing or stress relieving - softens and stabilizes carbon steel pipe without changing its ferrite-pearlite structure. Thi

Annealing is a heat treatment process in which steel is heated to a temperature above or below the critical point AC1, kept at that temperature for a certain period of time, and th
