Due to the excellent corrosion resistant properties, SA387 GRADE 91 Class 1 sheet is also an option for use in sour service environments. The material has good weldability and with its heat resistant qualities, the material is a highly versatile steel which can be used in numerous applications. Mechanical properties of SA387 GRADE 91 Class 1 Tensile strength, ksi [MPA]:85 to 110 [585 to 760]Yield strength, min, ksi [MPa]/(0.2% offset):60 [415]Elongation in 2 in. [50mm], min, %:18

S355ML material price, 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.

Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.

Our quality and service commitment: S355ML material price product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.

Our focus on quality has helped us create an efficiently organised production system, which can supply large-scale piping orders as well as tailor-made orders for smaller clients. We have also created a sales and support network which stretches from Asia to Europe, UAE, South Africa and South America.
