The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel ABS EH40 container ship steel products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our ABS EH40 container ship steel business. We also provide third-party inspection and approval services and inventory management for our customers.
The yield strength of AH36, DH36, ABS EH40 container ship steel, EH36, and FH36 Steel for high-strength hull structure is not less than 355MPa, and the tensile strength is 490 ~ 620MPa. The letter A, D, E, and F indicate the impact toughness that they can achieve at 0°C, -20°C, -40°C and -60°C respectively. The yield strength of Grade AH40, DH40, EH40, FH40 hull structural steel is not less than 390MPa, the tensile strength is 510 ~ 660MPa.
Low-alloy high-strength steel grades are designed to have quite good notch toughness for their intended structural use. The applicability of the notch toughness of specific grades of low-alloy high-strength steel is either based on existing use experience or combined with the results of the impact test of notched specimens. In order to meet the very strict requirements of certain applications, some ABS EH40 container ship steel, low-alloy high-strength steels produced have excellent notch toughness. For example, controlled hot rolling technology is usually used to produce low-alloy high-strength steel plates for the manufacture of welded line pipes. Such steel pipes need to meet the requirements of relevant standards for notch toughness.
Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest ABS EH40 container ship steel processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain ABS EH40 container ship steel by rolling method.
For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The ABS EH40 container ship steel, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.
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.
