Q550B steel is a low-alloy high-strength structural steel grade. Steel Q550A is not required for impact toughness test; Q550B is for impact toughness test at room temperature (20℃); Q550C is for 0℃ impact toughness test; Q550D is for impact toughness test at -20℃; Q550E grade is for impact toughness test Make impact toughness test at -40℃. The impact toughness test uses Charpy V-notch specimens. The impact toughness index is Akv.
The difference of chemical composition between BS700MC high strength alloy steel, Q420D steel and Q460D steel: Chemical composition of Q420D steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20, Al ≥ 0.015. Chemical composition of Q460D steel: C ≤ 0.20, Si ≤ 0.60, Mn ≤ 1.80, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.55, N ≤ 0.015, Mo ≤ 0.20, B ≤ 0.004, Al ≥ 0.015. The difference of mechanical properties between BS700MC high strength alloy steel, Q420D steel and Q460D steel: The mechanical properties of Q420D steel: yield strength ≥ 420 MPa, tensile strength 500-680 MPa. The mechanical properties of Q460D steel: yield strength ≥ 460 MPa, tensile strength 500-720 MPa.
The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. BS700MC high strength alloy steel, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.
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.
Expect in the BS700MC high strength alloy steel goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen BS700MC high strength alloy steel product development technology, excellent production team, hand strict quality control, sales and after-sales service.
