Alloy steel 1.4104

Alloy steel 1.4104

Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a pipe of various sizes and diameters, which is made of 1.4104 stainless steel. The supplier guarantees timely delivery of metal products to any address specified by the customer.

Technical specifications

The stainless chromium-containing steel of the ferritic-martensitic class 1.4104 is melted according to the European standard DIN EN, and is characterized by an elevated sulfur content. This improves the mechanical machinability of the material, but at the same time somewhat reduces the corrosion resistance and plastic deformability. Characterized by high resistance against intergranular corrosion. Strength properties are well regulated by changing the heat treatment regimes.

Urgency of application

Typical applications of 1.4104 steel are load-bearing pipe structures in railway transport, seamless pipes for boilers and heat exchangers, shut-off valves not produced by forging and stamping, and operating at temperatures up to 450… 500 0 С.

Chemical composition

The composition of steel 1.4104, according to the technical requirements of DIN EN 10204 / 3.1, includes the following elements (iron-base):

Carbon — no more than 0.16%;

Chrome — 16… 18%;

Manganese — no more than 1,25%;

Silicon — no more than 1%;

Molybdenum — 0,20… 0,60%;

Phosphorus — not more than 0.06%;

Sulfur — 0,15… 0,35%.

In the steel 1.4104 is allowed up to 0.1% nickel.
