What are the precautions during the cutting of SA573 Grade 70 steel for marine engineering

At the same time, the company operates a variety of products of related iron and SA573 Grade 70 steel for marine engineering steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained SA573 Grade 70 steel for marine engineering ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.

We have SA573 Grade 70 steel for marine engineering, marine steel CCS AH36 hot rolled plates 300tons in Shanghai stock. Specification: 12*1800*8000, 15*2100*8400, 15.5*3150*8200, 12.5*2380*7500, 21.5*2540*5200, 29*2160*6010, 17*1980*5720, 15.5*1700*8400, 18*2300*6750, 18.5*2680*8800, 14.5*1800*6500, 11*1890*6960, 17.5*1500*6790, 13.5*1900*6050, 14.5*1750*8300, 12*1830*9220, 13.5*1900*6050, 14*2000*6000, 13*2470*7780, 13*3020*6700, 12*1610*11240, 19*2090*7070, 14*1820*6500.

Compared with SA573 Grade 70 steel for marine engineering, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.

30CrMnSiA steel delivery status: SA573 Grade 70 steel for marine engineering, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.

"We can supply SA573 Grade 70 steel for marine engineering, hot rolled pressure vessel plate available sizeThickness from 5mm to 150mm Width: from 1,500mm to 2,500mm Length: from 6,000mm to 12,000mmFor plates thinner than 40mm normally supply as rolled. Plates above 40mm thick are normalised.Technical conditions: Ultrasonic tested as per SA 578 or any other as per requirement ; MTC acc to EN 10204 / 3.2; Charpy Impact tested at -20/-46 DegC.; Furnace Normalised."

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s SA573 Grade 70 steel for marine engineering domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the SA573 Grade 70 steel for marine engineering principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
