Q460E carbon steel plate sheet heat treatment

In terms of service, our service is a "one-stop" way of working. We have our own Q460E carbon steel plate sheet processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as Q460E carbon steel plate sheet cutting, welding, drilling, galvanizing, etc., at the lowest cost.

SAE4340, same as UNS G43400. Tensile strength σb ≥980(100) Yield strength σs ≥835(85), used to manufacture important parts with high strength and good plasticity. After nitriding treatment, make important parts with special functional requirements, such as shafts, gears, and gears. Firmware etc. Delivery Q460E carbon steel plate sheet in heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment.

After quenching and tempering, 40Cr alloy steel plate and Q460E carbon steel plate sheet sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel Q460E carbon steel plate sheet is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

Non-destructive flaw detection of steel plates is a test method for inspecting the Q460E carbon steel plate sheet surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used Q460E carbon steel plate sheet 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.

Hot Rolled Plates Products TestingBBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the Q460E carbon steel plate sheet raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."

Our company will accept the product quality objection registration record, pass it to the Q460E carbon steel plate sheet production unit and relevant departments, and timely coordinate the supervision of product Q460E carbon steel plate sheet quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
