ASTM A36 is a common mild steel(carbon structure steel grade). It is widely used in morden industry owning to its cheapest rolling cost and easiest welding. din EN 10149-2, ASTM A36 mild steel is equivalent to grade Q235B under Chinese steel standard, grade S235JR under European steel standard EN 10025-2, grade SS400 in Japanese steel standard. These mild steel plates and sections are commonly bolted and riveted in structural applications.

Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel din en 10149-2 not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized din en 10149-2 are higher than that of annealed din en 10149-2, but the elimination of internal stress is not as good as annealing. The normalizing operation of din en 10149-2 is simple, the cost is low, the productivity is high, and it is widely used in actual production.
