Industrial use GL-A hot-rolled steel strip

We are world class steel materials supplier. We are engaed in providing raw steel materials such as GL-A hot-rolled steel strip steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build GL-A hot-rolled steel strip long-term cooperation with you.

The commonly GL-A hot-rolled steel strip steels used to manufacture pressure parts of boilers mainly include low carbon steel, low alloy structural steel, low alloy heat-resistant steel, austenitic stainless heat-resistant steel and martensitic heat-resistant steel, etc. According to profiles, these boiler steels can be divided into boiler steel plates and boiler steel pipes. Our main GL-A hot-rolled steel strip boiler steel materials are as follows: A516 Gr 70, A537 class 1 , 16Mo3, Q345R, A204 grade B, A285C, ASTM A387, P355GH and so on.

Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of GL-A hot-rolled steel strip metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.

With our own engineers, metallurgists and CAD draftsmen, we can provide total support from design through to machined casting. OEM precision casting investment GL-A hot-rolled steel strip casting auto parts, customized investment casting auto parts, custom precision casting automobile parts, truck casting iron fitting parts.
Precision Casting: Tooling making → Wax pattern → Shall making → Chemical analysis → Pouring → Measurement & inspection → Heat Treatment → Processing → Finished product.

GL-A hot-rolled steel strip, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.

The results of adopting two-level GL-A hot-rolled steel strip service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and GL-A hot-rolled steel strip after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
