SCM440 steel pipe has better strength and good comprehensive mechanical properties after heat treatment, and is easier to process under heat treatment. It has excellent quenchability, can be deeply quenched and the temper brittleness tendency is less. This RINA grade B corrugated bulkhead steel product widely used in the production of high strength steel fasteners such as engine, pressure vessle, gear, transmission parts, shaft, arm, cold forging parts.
Q345R material is a special steel grade for pressure vessels with a yield strength of 340MPa. It has good comprehensive mechanical properties and technological performance. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 (16Mn) steel. In addition to the increased tensile strength and elongation requirements compared to Q345 (16Mn) steel, it also requires impact toughness. Q345R steel plate is currently the most widely used and most used steel plate for pressure vessels in China.
Non-destructive flaw detection of steel plates is a test method for inspecting the RINA grade B corrugated bulkhead steel surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used RINA grade B corrugated bulkhead steel steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
It is a modern high-tech professional enterprise integrating scientific research, RINA grade B corrugated bulkhead steel production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as RINA grade B corrugated bulkhead steel process technology development, technology transfer and related technical consulting and technical services.
After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
