Stainless steel 03H18N11 (the nearest foreign analogues — steel 304L, 1.4306) is a low-carbon austenitic steel, which is specially designed for its subsequent plastic deformation from rolling products into sheet parts of various sizes and configurations. Manufacture of steel products 03H18N11 is carried out in accordance with the technical requirements of GOST 9940−81. 304L — the designation of steel in the North American standard AISI, and 1.4306 — the numerical designation according to DIN EN. S30403 — steel number according to UNS specification. The steels in question are used in cases where reduced density values are required to reduce the weight of the structure or part. The use of steel 03H18N11 (steel 304L, alloy1.4306) eliminates the need for post-
welded annealing, which significantly increases the corrosion resistance (up to 600 0 C). The lack of steels is a sensitivity to high-temperature chlorine-containing media that can cause surface cracking.
Urgency of application
These steels show excellent resistance in various atmospheres, and also provide long-term corrosion resistance, therefore they are used in structures operating at elevated temperatures. Steel grade 03H18N11 (steel 304L or 1.4306) are non-magnetic, characterized by high ductility and sufficient corrosion resistance under conditions of periodic temperature fluctuations. Therefore, these brands of stainless steels are used in the production of working parts in the food industry, in the manufacture of medical and pharmaceutical equipment, in machines and apparatuses of petrochemical production. Some application of the data has also been received in construction, where they are used in the design of public and social and cultural buildings.
The composition of steel grade 03H18N11 includes the following elements (iron — the rest):
Carbon is not more than 0.03%;
Chrome — 17.5… 20.0%;
Nickel — 8… 12%;
Manganese — no more than 2%;
Silicon — no more than 1%;
The bound nitrogen is not more than 0.1%.
The amount of metallurgical impurities — phosphorus and sulfur — is limited to 0.045% and 0.030%, respectively.
