What is hardox 500 density equivalent steel in GB standard

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

Q345qC steel plate is the steel plate of bridge structure, the implementation standard is GB / T 714-2015 standard. HARDOX 500 density, Q345qC-Z25 steel: Q represents the yield strength, 345 represents the small yield strength, the unit is MPa, q is short for the bridge, C quality grade, corresponding to the corresponding impact temperature and impact work value, Z is the Z-direction performance that is the performance of the steel plate thickness direction, Z25 is the Z-direction Performance level requirements.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. HARDOX 500 density, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.

15CrMo alloy steel plate is pearlite structure heat-resistant steel, which has high heat strength (δb≥440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel HARDOX 500 density is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc.

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 HARDOX 500 density 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 HARDOX 500 density product development technology, excellent production team, hand strict quality control, sales and after-sales service.
