What is the astm a588 gr a BBN Steel advantages

In terms of service, our service is a "one-stop" way of working. We have our own astm a588 gr a processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as astm a588 gr a cutting, welding, drilling, galvanizing, etc., at the lowest cost.

BBN steel have large stock of hot rolled plate astm a588 gr a. Our products are exported to many countries: South Africa, France, Zimbabwe, Egypt, Mexico, Pakistan, Azerbaijan, Trinidad & Tobago,Tunisia, Chile, Angola, Belarus, Sri Lanka, Afghanistan, Turkey, Hong Kong, United States, Bahrain, Brazil, Jordan, Czech Republic, Indonesia, Denmark, Canada, Taiwan, Iran, Tibet, Nigeria, Croatia, Kazakhstan, Poland, Iraq, Yemen, Bolivia, Serbia, Finland, Nepal, Morocco, Ireland, Singapore, Italy, New Zealand, Namibia, Saudi Arabia, Mexico, Qatar, Lebanon, South Korea.

Heat treatment advantages of astm a588 gr a, SA516 Gr 70 pressure vessel steel:
1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased.
2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness.
3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition.
4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and astm a588 gr a pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
