high-strength precision stainless steel strip is a high-precision product, and has very strict standards for the brightness, roughness, mechanical properties, hardness, precision tolerance and other indicators of the display, so it has become a leader in stainless steel strips.
1. The concept of precision stainless steel strip
Usually we call the heat-resistant cold-rolled stainless steel strip with a precision of 600-2100N/mm2 and a thickness of 0.03-1.5mm as a high-strength precision steel strip. Time craft is quite special.
The concept, characteristics and production standards of 304 high-strength precision stainless steel strip
2. Characteristics of 304 precision stainless steel strip
Since this product belongs to the field of specialization, through its parameters and production standards, we can understand its characteristics in the following aspects:
1) The width is below 600mm;
2)The thickness tolerance is ±0.001mm, and the width tolerance is ±0.1mm.
3) The surface quality of the product can meet the needs of various occasions, such as ordinary 2B surface, BA surface and even special surface.
4)It has high mechanical properties, and the appropriate yield stress and strength can be formulated according to the needs of customers.
5)The grain size is relatively uniform. When the product is fully annealed, the grain size needs to be controlled at 7.0-9.0. At the same time, the strength performance is also relatively balanced, and the hardness fluctuation needs to be controlled between ±5-10Hv.
6)In addition, 304 high-strength precision steel strips have high requirements for straightness and edge quality.
3. Production standards for steel strips
1) ASTM A666: This standard covers austenitic stainless steel strip materials, including type 304, and specifies the requirements for chemical composition, mechanical properties, dimensions, and tolerances.
2) EN 10088: This European standard provides the technical delivery conditions for stainless steel strip, including grade 1.4301, which corresponds to AISI 304. It covers dimensions, tolerances, surface conditions, and mechanical properties.
3) JIS G4305: This Japanese standard outlines the cold-rolled stainless steel strip specifications, including type SUS304, which is equivalent to AISI 304. It covers chemical composition, mechanical properties, dimensions, and tolerances.
Of course, each manufacturer has its own production standards too.Many production companies will establish their own production standards based on cold-rolled steel strip standards or according to customer needs. However, many manufacturers generally feel that the product has higher requirements on deviation, which can meet the needs of various customers.
