Cause of corrosion pits on bp370 steel heat treatment

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of BP370 steel heat treatment steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main BP370 steel heat treatment production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

Available steel plates: carbon structural steel, low-alloy high-strength steel, steel plates for bridges, steel for building structures, steel angles for shipbuilding and offshore platforms, steel sheets for boilers and pressure vessels, BP370 steel heat treatment steel plates for molds, steel plates and strips for alloy structures, corrosion-resistant steel, wear-resistant steel, pipeline steel for oil and gas transportation.There are more than 300 domestic and foreign steel grades in our supply list.

Spring steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. BP370 steel heat treatment, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. Spring steel has hot rolled steel, cold drawn steel, cold rolled steel strip and so on. How much a ton of spring steel is related to the grade of spring steel, the market situation and the manufacturer.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the BP370 steel heat treatment steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the BP370 steel heat treatment steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

Chemical composition of 65Mn steel: C 0.62-0.70, Si 0.17-0.37, Mn 0.90-1.20, Cr ≤ 0.25, Ni ≤ 0.30, Cu ≤ 0.25. 65Mn steel mechanical properties: tensile strength: ≥735 Mpa, yield strength: ≥430 Mpa, elongation after fracture: ≥9%, reduction of area: 30%, impact absorbed energy: no impact. BP370 steel heat treatment, 65Mn steel has high strength, high hardenability, less decarburization tendency, overheat sensitivity, easy to produce quenching cracks and temper brittleness. 65Mn steel is used for making various flat and round springs, leaf springs, spring rings, valve springs, steel wire cold coil springs, clutch springs of light trucks and cars.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
