304L grade stainless steel is a version of 304 quality stainless steel with a carbon content of less than 0.03%. This stainless steel quality, which is almost identical to 304 grade stainless in terms of its basic properties, is recommended instead of 304 quality where the source is dense.
304L instead of 304 quality, 304L quality 304 quality stainless material is no objection to use. However, the choice of 304L grade stainless steel where the source is dense would be more appropriate to prevent carbon carbide. This quality, which has a low carbon ratio, is least affected by the excessive heat generated during welding and minimizes the carbon carbide.
Grading Quality Characteristics
This quality, which is quite sufficient for daily use and standard production, is very similar to 304 quality in terms of its basic features. In the welded areas, the corrosion resistance of the welded parts is higher than that of 304 quality, since less quality of 304L quality is observed. 304L grade stainless steel is recommended especially for welded areas and is not preferred in more corrosive environments. Instead of 304L quality stainless steel in more demanding conditions, 316L, 316Ti or duplex (1.4462) grade stainless steels can be preferred.
This stainless steel quality, which is often sufficient for mechanical strength, is not preferred in places where high yield and breaking strength are desired. When mechanical properties come to the fore, different quality stainless steels may be preferred by considering the material structure.While parts such as 420, 431 and 630 may be preferred in the parts requiring heat treatment, for example, in marin (sea) products, duplex (1.4462) grade stainless steels may be preferred.
Vulnerability to be beaten:
This material, which has good quality forging, is less brittle since it contains less carbon than 304 quality and it can be shaped and shaped more easily according to 304L 304 quality.
This material, which is very good weldability, should be preferred to avoid rusting especially in the welded areas. In the more difficult conditional places, 316L grade stainless steel, which can be named as an upper version, may be preferred.
In terms of machinability
