How to ensure the quality of 65G hot rolled steel sheets
Steel is a universal material for the production of rolled metal. Because it is distinguished by its favorable cost and fairly high strength, the ability to withstand a wide range of temperatures, high humidity, as well as extreme loads.
On its basis, a whole range of products are produced: from small parts to rolled sheet metal. Presented on https://www.metallosnab.com.ua/cherniy-metall/listi/list-goryachekatanniy/list-goryachekatanyj-65g/ steel sheets are produced by the hot-rolled method. This allows you to obtain a large volume of products in the shortest possible time, while maintaining all its functional properties and characteristics.
How do you understand that when ordering hot-rolled steel sheets, you are getting truly high-quality, reliable and durable rolled metal? We have compiled a list of key criteria that you should pay attention to.
Check rolled metal for compliance with GOST
Hot-rolled steel sheets today are produced in accordance with technical standards, which regulate:
- chemical composition;
- mechanical properties;
- parameters of length, width and thickness of the sheet;
- possible tolerances and errors.
Each manufacturer must have documentation and certificates on hand that confirm the compliance of the sheets with established standards: compliance with the specified steel grade, regulated errors that should not exceed the values specified in the certificate.
Carefully inspect the rolled metal
Before purchasing hot-rolled steel sheets, it is important to conduct a visual inspection of the base for defects on the surface. Pay attention to:
- The very base of the sheet. It should be smooth and uniform, without cracks or delaminations. And especially rust, scratches, and so on.
- The edges of the sheet. Must be perfectly even and smooth, without sharp protrusions, delamination, indicating non-compliance with the rules for cutting rolled metal.
- The thickness of the sheet material, which should be the same at all points.
Choose a reliable manufacturer
Today, suppliers of hot-rolled steel sheets also work online. When choosing a metal rolling company, pay attention to its reputation and customer reviews.
It is advisable to cooperate with suppliers who have many years of experience and guarantee an individual and responsible approach to each client.
At the same time, even high-quality and certified hot-rolled sheets can fail early. If you do not take into account their further operating conditions. When choosing the markings and parameters of sheet metal, pay attention to what mechanical load it will be subjected to and what environment it will be in: humidity, possible contact with chemicals, temperature, etc.
