Alloy 1.4307 pipe, wire, circle
Supplier — AvekGlob Company — offers at various prices from the manufacturer various bulk metal — pipes, wires or wheels, which are made of 1.4307 stainless steel. The supplier guarantees timely delivery of metal products to any address specified by the customer.
Stainless steel grade 1.4307 is austenitic grade steel, also known as AISI 304L. It is considered one of the most common brands of stainless steels, which is used for the production of household utensils. Steel is characterized by a reduced percentage of carbon, which leads to an increase in corrosion resistance. It is used in long-length pipelines and structures to improve weldability. Some products are available as double certified material that meets the criteria for both AISI 304 (household version) and AISI 304L (industrial version). Steel is not magnetic.
High resistance to intergranular corrosion and heat resistance for steel grade 1.4307 are preserved at temperatures up to 550 0 С (for short periods up to 750… 800 0 С).
Urgency of application
Steel grade 1.4307 is considered universal: it can be made of almost all products. which function in any corrosive medium with an average and medium-high concentration of chemically aggressive components. Typical products are welded devices, medical instruments, construction and architectural structures.
The steel grade 1.4307, according to the technical standards ASTM SS2333, includes the following elements (iron-base):
Carbon is not more than 0.03%;
Chrome — 18… 20%;
Nickel — 8… 12%;
Manganese — no more than 2%;
Silicon — no more than 1%;
Phosphorus — not more than 0.045%;
The bound nitrogen is not more than 0.11%;
Sulfur — no more than 0,035%.

Technological features of processing and assortment
Stainless steel 1.4307 is available in a wide range of rolling profiles and forgings, while bulk rolling is available in both cold-drawn and annealed conditions. This steel is well welded, however, to ensure the strength of the welded joint, it is recommended to use electrodes with AWS E / ER308, 312 or any other low-carbon coating, which prevents the accumulation of carbides at the boundaries of the weld zone. Steel 1.4307 has an increased plasticity, and is well deformed in the cold state. Before cold forming of the workpiece, it is advisable to subject it to oxalation. The temperature range of forging is 1050… 1100 0 С.
