In 2016. Our company offer 1200 tons API 5L GR.B hot rolled coil to Bangladesh——100 tons for 3.9*625mm, and 1100 tons for 7*683mm. It is one tender project, we get the tender at the end of 2015, and arrange the production in 2016. They required the tolerance of thickness is +0.1/-0.2mm, and width tolerance is +/-0.5mm, which is a very high requirement for coil tolerance, but our mill handling this very well. and our Q/C department witness all of the process.

The company will regularly hold the award ceremony for excellent employees. he award-winners prove their excellence and the team’s excellence with api 5l psl1 x80 grade great achievements.On Oct., 2018 the Management star is Ms. Sherry from International Trade Department. The sales star is Ms. Katrina from International Trade Department. Under the guidance of Ms. Sherry, the old customer maintenance team of api 5l psl1 x80 grade BBN steel completed 309% sales task in Oct., 2018. Ms. Katrina has been using her own actions to interpret the "pursuit of excellence, continuous innovation" spirit of BBN enterprise.

The quenching of steel plate is to heat the api 5l psl1 x80 grade steel to above the critical temperature, keep it warm for a period of time, and then quickly put it into the quenching agent, so that its temperature drops suddenly, and the speed of rapid cooling is greater than the critical cooling rate, and obtain the heat treatment method of imbalanced structure with martensite as the main body. Quenching increases the strength and hardness of steel, but reduces its plasticity. Quenching commonly used quenching agents are: water, oil, alkaline water and salt solutions.

Stainless, mild steel, high strength, aluminum, and numerous other types of processed steel api 5l psl1 x80 grade are all used in our metal forming services. We manufacture frame channels, stair pans, steel structures, pressure vessel components, rolling plates, and many other products servicing the automotive, construction, ornamental, oil storage and industrial markets.
