LSAW pipe range of a242 type 1 hot-rolled corrosion-resistant angle steel steel

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the a242 type 1 hot-rolled corrosion-resistant angle steel project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of a242 type 1 hot-rolled corrosion-resistant angle steel customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

A572-50 steel I-beam is widely used in construction and architectural applications because it can provide more strength unit weight. The low content of niobium, vanadium and other alloy elements optimize its strength and atmospheric corrosion performance. Because of its high strength of 50000 Ksi yield strength, a242 type 1 hot-rolled corrosion-resistant angle steel a572-50 steel I-section steel is more and more replacing ordinary carbon steel beams such as A36, and A36 section steel needs to be thickened to meet the strength requirements. a242 type 1 hot-rolled corrosion-resistant angle steel ASTM 572 steel I can be used in other grades, such as 42, 55 and 60.

The requirements for toughness impact energy of a242 type 1 hot-rolled corrosion-resistant angle steel, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.

In actual processing applications, the processing a242 type 1 hot-rolled corrosion-resistant angle steel thickness of flame cutting ranges from 6 to 200 mm, and the a242 type 1 hot-rolled corrosion-resistant angle steel cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting a242 type 1 hot-rolled corrosion-resistant angle steel with a certain thickness above 10mm.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
