Supplier — AvekGlob Company — offers sheet and tape made of stainless steel AM-355 (ams 5547) at an affordable price from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Steel AM-355 (ams 5547) is a chromium-nickel-molybdenum stainless steel. Depending on the heat treatment regime, it can have an austenitic or martensitic structure. A peculiarity of the properties of this steel is the optimal combination of strength parameters characteristic of the strength of heat-treated martensitic grades with corrosion resistance of some grades of austenitic grades of chromium-containing steels.

Urgency of application

Steel AM-355 (ams 5547) is used for the production of blades, knives, industrial cutters, discs, blades and rotors, shafts and the like, where high strength is required at intermediate elevated temperatures. The operating temperature of the application should not exceed 535… 540 ⁰ С.

Chemical composition

In accordance with the specification AMS 5547, steel AM-355 (ams 5547) has the following chemical composition (iron — the rest):

Carbon — 0.10… 0.15%;

Chrome — 15… 16%;

Nickel — 4… 5%;

Molybdenum — 2.5… 3.25%;

Manganese — 0.5… 1.25%;

Silicon — up to 0,5%;

Phosphorus — up to 0.040%;

The bound nitrogen is 0.07… 0.13%;

Sulfur — up to 0,030%.

Physical and mechanical properties

Density, kg / m ³ — 7920;

Specific heat capacity, J / kggrad — 500;

Coefficient of thermal conductivity, in the temperature range 20… 400 ⁰ С, W / megade — 16,5;

The coefficient of thermal expansion in the temperature range 20… 400 ⁰ С, μm / deg — 12,6;

Strength limit, MPa — 1165… 1275;

Yield strength, MPa — 980… 1020;

Hardness according to Rockwell (scale C), no more than 48;

Relative elongation at a stretching,% — 12… 19;

Technological features of processing and assortment

Stainless steel AM-355 (ams 5547) is available in a wide range of profiles, with rolling available both in cold-drawn and annealed conditions. When cold stamping, steel is hardened. The working range of forging temperatures is 900… 980 ⁰ С. Weldability is possible with all types of welding, except for gas acetylene. To avoid corrosion cracking after welding, the products are annealed.
