What is the SA514 Gr Q steel material machining

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep SA514 Gr Q steel material processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and SA514 Gr Q steel material steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

Q690D grade is a low-alloy high-strength structural steel, belonging to the structural steel category. Q690D steel plate executive standard: GB/T16270-2009. Q is the expression of yield strength, 690 is its lower limit yield value, and D is its grade. This grade also has a higher yield strength and tensile strength. Q690 series grades also include Q690C, Q690D, Q690E, Q690F. Delivery status of steel SA514 Gr Q steel material: It should be delivered in quenched and tempered state. In addition, this grade can be delivered according to some special requirements of customers, but it should be indicated in the contract.

Shipbuilding steel plates are used to manufacture the hull of marine and inland ships. High strength, plasticity, toughness, cold bending performance, welding performance and corrosion resistance are required for shipbuilding steel plates. Boiler steel plates are used to manufacture various boilers and important accessories. As the boiler steel plate works under medium temperature (below 350℃) and high pressure, it is also subject to impact, fatigue load and water and gas corrosion. The SA514 Gr Q steel material, boiler steel plate is required to ensure a certain strength and have good welding and cold bending properties.

Laser cutting is that the horizontal laser beam emitted by the laser changes into a vertical downward laser beam through the 45° total reflector, and then focuses through the lens, forming a tiny spot at the focal point. When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material such as SA514 Gr Q steel material, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.

Chemical elements of 42SiMn steel: C: 0.39-0.45, Si: 1.10-1.40, Mn: 1.10-1.40. Mechanical properties of 42SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 40; impact energy: 47J. 42SiMn steel belongs to alloy quenched and tempered steel with good properties, high strength, wear resistance and hardenability. Under certain conditions, the strength, wear resistance and hot working performance of 42SiMn steel are better than 40Cr steel, SA514 Gr Q steel material, and can be used instead of 40CrNi steel.

We have replenish steel materials stocks, now there are huge stocks of S355JR, A36, SA514 Gr Q steel material A572 Gr 50, 16Mo3, A516 Gr 70, ABS grade A, AH32, AH36, EH36, SPA-H, SG295,SM700C etc steel materials. We can arrange delivery for those stock steel products within short time. Meanwhile, we also provide further processing for the SA514 Gr Q steel material steel materials, such as cutting, drilling, bending, welding, etc. Please do not hesitate to contact us if you have any steel demands.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent SA514 Gr Q steel material products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the SA514 Gr Q steel material technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
