wear resistance of nm400 charpy impact test temperature

On Jan. 31, 2019, BBN steel held the annual meeting with all employees, family members, and friends. It is a moment of joyand it is a moment to summarize the past and look forward.Looking back on 2018, BBN steel exported wear resistance of NM400 more than 2 million tons of steel materials to all parts of the world and made outstanding contributions to infrastructure construction at home and abroad. In 2019, BBN steel will make persistent efforts and forge ahead.

Analyze the advantages and disadvantages of the products against the competitive products. Understand the industry situation and future trend. Understand the wear resistance of NM400 product brand positioning appeal point, focus on the crowd and development direction. Understand the layout of each market area, and form a big strategic layout view. Understand the basic operation and assessment standards of work responsibilities. Understand the situation of the cooperative customers.

GB / T1591 Q345D steel is a commonly used low alloy plate in China. It is equivalent to grade S355J2 in Germany and ASTM A529MGr50 in the United States, with slightly different chemical composition and the same mechanical properties. Under normal delivery conditions, wear resistance of NM400, Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.

The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. wear resistance of NM400, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.

In year 2015, we supplied 950 tons S355J0 angle steel to Egypt government. We have cooperation with local government for more than 3 years. Every year, they would order more than 3000 tons of wear resistance of NM400 steel from our company.

The high strength wear resistance of NM400 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 wear resistance of NM400 ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
