Magnetic stainless steel

Another type of electrical pressure transducer is a variable-reluctance device. The deflections of a diaphragm of magnetic stainless steel are sensed by two inductance pickup coils. With ac-bridge circuitry, this transducer delivers a full-scale output of 40 mV per volt for a variety of ranges from 0 4 Torr (0- 0.08 PSIA) to 0- 3200 PSIA. 

Anval Metal Powder for Plastic Filler - 304, 316 (non-magnetic stainless steel), 410L, 410, 420 (magnetic stainless steel). Spherical particles obtained by gas atomization of alloys containing different proportions of Cr, Ni, Mo, and Fe. Obtained spherical particles are classified to the required sizes. Materials can be produced to the required size in a range from 15 to 1000 pm. 

The stirrers have two sets of blades and are made of magnetic stainless steel. They rest on supports located on the ends of membrane-containing cylinder thus they do not come into contact with the membrane, avoiding abrasion of the sinter surface. 

The sample could be agitated by a small stirrer which consisted of a magnetic stainless-steel rod, of slightly smaller diameter than the bore of the glass capillary tube. A small length of drill rod was spot welded on to the steel rod. The stainless-steel rod was located in the tube just above the compressor block, with the drill rod extending into the hydrocarbon sample at the top of the tube.

Gobalt is also used in other magnetic steels and stainless steels, and in alloys used in jet turbines... 

It is used in arc-welding rods for stabilized grades of stainless steel. Thousands of pounds of niobium have been used in advanced air frame systems such as were used in the Gemini space program. The element has superconductive properties superconductive magnets have been... 

In addition, the magnetic characteristics of a material can change as a function of stress (e.g., unannealed series 316 stainless steel can be magnetic after machining), temperature, pressure, and physical and chemical treatment. Therefore, when two paramagnetic materials with similar magnetic susceptibilities are to be separated, the possibility that pretreatment will facilitate subsequent separation should be studied. 

Isolation of the mills, use of nonsparldng materials of construction, and magnetic separators to remove foreign magnetic material from the feed are useful precautions (Hartman, Nagy, and Brown, U.S. Bur. Mines Rep. Invest. 3722, 1943). Stainless steel has less sparking tendency than ordinary steel or forgings. 

Non-magnetic insulator supports of SMC/OMS aluminium or stainless steel etc. 

The device consists of a low thermal mass test cell of 110 ml volume. This is made of stainless steel with a 0.015-mm wall thickness, but test cells made from other materials can be used. The contents of the cell are mixed using either a magnetically driven stirring bar or a direct drive agitation test cell. The test cell is... 

Niobium finds use in the production of numerous stainless steels for use at high temperatures, and Nb/Zr wires are used in superconducting magnets. The extreme corrosion-resistance of tantalum at normal temperatures (due to the presence of an exceptionally tenacious film of oxide) leads to its application in the construction of chemical plant, especially where it can be used as a liner inside cheaper metals. Its complete inertness to body fluids makes it the ideal material for surgical use in bone repair and internal suturing. 

Total world production of nickel is in the region of 1.0 million tonnes pa of which (1995) 25% comes from the former Soviet Union, 18% from Canada, 12% from New Caledonia and 10% from Australia. The bulk of this is used in the production of alloys both ferrous and non-ferrous. In 1889 J. Riley of Glasgow published a report on the effect of adding nickel to steel. This was noticed by the US Navy who initiated the use of nickel steels in armour plating. Stainless steels contain up to 8% Ni and the use of Alnico steel for permanent magnets has already been mentioned (p. 1114).
