Embodiment Construction

[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] The invention provides a technical solution: a non-magnetic austenitic stainless steel casting, characterized in that: it is composed of the following raw materials in parts by weight: C, Si, Mn, Cr, Ni, S, P, N and Fe;

[0020] Wherein: C is 0.01-0.08 weight part, Si is 1.5 weight part, Mn is 1.5 weight part, Cr is 18.0-19.0 weight part, Ni is 8.0-9.0 weight part, S is 0.03 weight part, P is 0.045 weight part, N is 0.1 part by weight, and the balance is Fe.

[0021] Made with the following steps:

[0022] Step 1. Add ordinary austenitic stainless steel trim and die head material to add nickel plate required by chemical composition;

[0023] Step 2. When the molten steel temperature reaches 1580°C, add the required ferromolybdenum and all...

Abstract

The invention provides a nonmagnetic austenitic stainless steel casting. The nonmagnetic austenitic stainless steel casting is characterized by being composed of raw materials including, by weight part, 0.01 part to 0.08 part of C, 1.5 parts of Si, 1.5 parts of Mn, 18.0 parts to 19.0 parts of Cr, 8.0 parts to 9.0 parts of Ni, 0.03 part of S, 0.045 part of P, 0.1 part of N and the balance Fe. Compared with the prior art, the casting has the following beneficial effects that the manufactured austenitic stainless steel has the advantages of austenitic stainless steel, has no magnetism, has high toughness and plasticity and is excellent in welding property, the good corrosion resistance and high temperature strength are achieved, and the good inoxidizability and the good pressure machining property are achieved.

Description

technical field [0001] The invention is a non-magnetic austenitic stainless steel casting, which belongs to the technical field of mechanical manufacturing. Background technique [0002] Stainless steel is the abbreviation of stainless and acid-resistant steel. The steel grades that are resistant to weak corrosive media such as air, steam, and water, or have stainless properties are called stainless steel; The steel type is called acid-resistant steel. Due to the difference in chemical composition of the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical medium corrosion, while acid-resistant steel is generally stainless. [0003] The manufacturing process of stainless steel castings in the prior art is complex and difficult to popularize. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a non-magnetic austenitic stainless steel ca...
