Our quality control department will do inspection for details of the steel materials NV D40 hull steel material before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
RAEX400 steel is a hardened wear-resistant steel material with an average grade of 400HBW and a Brinell hardness. The microstructure of this wear-resistant steel is a martensite structure, which can ensure the high hardness and tensile hardness of the steel plate. The hardness of RAEX400 is 2.5 times that of S355 structural steel, NV D40 hull steel material. Despite its high hardness and high strength, RAEX400 steel can be formed by free bending or hemming, and has good weldability.
DIN 17100 St37-2 steel plate belongs to the carbon and low alloy high strength steel plate. We can supply the different sizes of NV D40 hull steel material, DIN 17100 St37-2 steel plate. And the rolling size of DIN 17100 St37-2 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the DIN 17100 St37-2 steel coil thickness should not exceed 25 mm.
Specification range of available steel NV D40 hull steel material: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates NV D40 hull steel material can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
The high strength NV D40 hull steel material low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of NV D40 hull steel material ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
