Q235NH tower steel sheet astm welding

The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.

The ASTM A572 Q235NH tower steel sheet specification refers to high-strength low-alloy steel plates used in structural buildings. Among the five steel grades 42, 50, 55, 60 and 65, grade 50 is the most common in applications requiring higher strength and lighter weight. One of the Q235NH tower steel sheet steels, the steel plate of this brand other than ordinary carbon steel is used, so that the steel structure has the same steel strength, but the weight is lighter.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of Q235NH tower steel sheet welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.

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. Q235NH tower steel sheet, 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.

Steel logistics takes “steel” as the carrier, “logistics” as the operation, and “information” as the core. It integrates steel trade, e-commerce, and tripartite logistics as one. The flow of funds, information, and logistics promote each other and integrate with each other. Construction industry, metallurgy industry, information industry, modern logistics cross-industry. Our logistics service team will make sure our goods delivered to the leaving port on time.Makes you worry-free after sales.

We have a good inventory system because of which the alloy steel plates and structural steel sheets are supplied and delivered to our customers on time. Our alloy steel plate is significantly affordable than austenitic Q235NH tower steel sheet stainless steel which helps to reduce maintenance and full life costs – as well as improved safety over standard boilerplate.
