S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. A572 grade 42 ms steel coil, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265. Tensile strength: 450-680MPa.
Q235NH corrosion-resistant steel plate full name: atmospheric corrosion-resistant hot continuous rolled steel, also known as Corden steel, widely used in: containers, power plants, chimney and railway engineering, such as large outdoor sculpture steel. The corrosion-resistant steel plate (i.e. atmospheric corrosion resistant steel) is a low-alloy steel series with low price and good quality, which is between ordinary steel such as A572 grade 42 ms steel coil and stainless steel. The corrosion-resistant steel can be continuously developed and innovated after being integrated into modern metallurgical new mechanism, new technology and new process. It is one of the series of steel with world advanced super steel technology.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A572 grade 42 ms steel coil steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This A572 grade 42 ms steel coil method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
Expect in the A572 grade 42 ms steel coil 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 A572 grade 42 ms steel coil product development technology, excellent production team, hand strict quality control, sales and after-sales service.
The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
