09MnNiDR steel plate is a low-alloy high-strength steel plate with excellent low-temperature toughness and good welding performance. It is widely used in petroleum, chemical industry, marine engineering and other fields.
09MnNiDR: It is a steel plate for low temperature pressure vessels. "D" is the first letter of low Pinyin "R" is the first letter of Rong Pinyin 09MnNiDR, delivery status: normalizing or normalizing + tempering, quenching + tempering - 70 degree low temperature impact.
Comparison between 09MnNiDR steel plate and SA537CL1
Compared with the American standard low-temperature container plate SA537CL1, its low-temperature impact requirement is -40 degrees, and 09mnnidr has outstanding advantages over it in terms of mechanical properties and application range. Domestic 09mnnidr has been able to replace imported products
The main feature of the steel plate is that the carbon content is 0.09% and it contains chemical elements such as manganese (Mn) and nickel (Ni), which allows it to maintain good toughness and strength in low temperature environments and is not prone to brittle fracture.
09MnNiDR steel plate According to the GB/T3531-2014 standard, the chemical composition and mechanical properties of 09MnNiDR steel plate have strict regulations. For example, its carbon content should not be greater than 0.12%, tensile strength should not be less than 440MPa, yield strength should not be less than 295MPa, elongation should not be less than 21%, etc. At the same time, for steel plates with thickness greater than a certain value, ultrasonic testing is required to ensure quality.
