Abstract
The invention relates to a low-nickel stainless steel alloy. The low-nickel stainless steel alloy material comprises the following components by weight percent: 0.05-0.1% of carbon, 0-0.01% of sulfur, 0-1.0% of silicon, 0-0.01% of phosphorus, 18.5-19.5% of chromium, 7.5-8.5% of manganese, 0.25-0.3% of nitrogen, 0.003-0.008% of boron, 0.008-0.1% of germanium or yttrium and the balance being ferrum and inevitable impurities.
Description
Technical field
The present invention relates to the Stainless Steel Alloy field, refer to especially a kind of low nickel stainless steel alloy.
Background technology
Stainless steel is divided into martensitic steel by structural state, ferritic steel, austenitic steel, austenite-ferrite steel and PH Stainless Steel.Wherein ferritic stainless steel has erosion resistance, toughness and weldability; Austenitic steel has corrosion-resistant, has simultaneously good plasticity, toughness, welding and erosion resistance; Austenite-ferrite has the advantage of austenite and ferritic stainless steel concurrently, and has superplasticity, particularly for having austenite-ferrite, wherein nickel is expensive, in order to reduce cost, should reduce the content of nickel, increase the content of manganese and nitrogen, can when keeping the stainless steel performance, reduce the cost of steel alloy.
Summary of the invention
The objective of the invention is by the technical program, have good erosion resistance and thermoplastic while and reducing the preparation method of stainless steel alloy material and this alloy material of cost.
The present invention is achieved by the following technical solutions:
A kind of low nickel stainless steel alloy, the composition that this alloy material comprises and weight percentage are: the carbon of 0.05-0.1%, the sulphur of 0-0.01%, the silicon of 0-1.0%, the phosphorus of 0-0.01%, the chromium of 18.5-19.5%, the manganese of 7.5-8.5%, the nitrogen of 0.25-0.3%, the boron of 0.003-0.008%, the germanium of 0.008-0.1% or yttrium, rest part are iron and inevitable impurity.
Described Stainless Steel Alloy by weight percentage composition also comprises the nickel of 0.2-0.5%.
Described Stainless Steel Alloy by weight percentage composition also comprises at least a in the molybdenum of 0.2-0.5% or the tungsten.
The ratio of manganese and nitrogen is 30: 1 in the described Stainless Steel Alloy.
The invention has the beneficial effects as follows:
Compared with prior art, alloy material of the present invention is the two-phase region at the steel of its composition range 1000-1300 ℃ of scope, and cost is compared cost with prior art.
