Welcome to BBN High Strength Steels Factory
The company will also put Georgetown steelworks on "care and maintenance mode" and temporarily lay off or redeploy about 130 employees working at the steelworks and contractors while some 1.8928 material equivalent maintenance employees will be on staff during the closure. It is stated that unemployment insurance and state-based unemployment support will be available immediately to workers affected by these changes.
Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of 1.8928 material equivalent service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.
A517 Grade Q steel is a low-alloy pressure vessel grade rolled steel plate that conforms to A20 manufacturing specifications; in an open-hearth under oxygen or via electric arc production. These plates have a maximum thickness of 32mm 1.8928 material equivalent and must be subjected to robust heat analysis to verify its elemental composition. Process managers must carefully control the levels of carbon, manganese, phosphorous, sulfur, silicon, chromium, molybdenum, boron, vanadium, and titanium in order to guarantee compliance – thus performance.
NM450 steel plate thickness≦80mm. 1.8928 material equivalent, NM450 wear-resistant steel plates are used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.NM450 Cchemical composition: C≤0.35; Si≤0.70; Mn≤1.70; P≤0.025; S≤0.010; Cr≤1.10; Ni≤0.80; Ti≤0.050; Mo≤0.55; B: 0.0005-0.006; Al≥0.010. Mechanical properties: Tensile strength Rm / MPa ≧ 25; -20 ℃ impact energy absorption (longitudinal) KV2 / J ≧ 24Surface Brinell hardness HBW: 420-480
The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate 1.8928 material equivalent EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
