The application of laser processing technology in processing of SA573 Grade 70 structural carbon steel angle bar

ASTM A36 is a common mild steel(carbon structure steel grade). It is widely used in morden industry owning to its cheapest rolling cost and easiest welding. SA573 Grade 70 structural carbon steel angle bar, ASTM A36 mild steel is equivalent to grade Q235B under Chinese steel standard, grade S235JR under European steel standard EN 10025-2, grade SS400 in Japanese steel standard. These mild steel plates and sections are commonly bolted and riveted in structural applications.

We are a professional SA573 Grade 70 structural carbon steel angle bar steel raw material supplier with a history of 17 years. After years of development, the company's steel plates and coils are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields around the world. With good product SA573 Grade 70 structural carbon steel angle bar quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.

The hot rolling method is to heat the SA573 Grade 70 structural carbon steel angle bar steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of SA573 Grade 70 structural carbon steel angle bar rolling process is usually called semi-finished product production, also called blank production.

Our strutural steel plates are not attacked easily by the chemicals in harsh weather. They are a hard, strong, and durable product. Their characteristics are tested through tests. We perform hardness, pmi, micro, chemical, mechanical, macro, ultrasonic test and more. We pack carbon steel plates, SA573 Grade 70 structural carbon steel angle bar, hot rolled plates, structural steel sheets safely to maintain their good performance so that they serve longer than usual.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
