Carbon steel strip

BS 6536 1985 refers to four grades of carbon steel strip coated with Al-Si alloys containing 5-11 wt.% Si. The availability of the steel grades allows account to be taken of the type and degree of forming which is to be applied to the coated steel. Various coating masses are supplied in the range 40-180 g/m which may be additionally protected by a chromate passivation treatment. 

Tinplate is a low-carbon steel strip product coated on both sides with a thin layer of tin. Several million tons of tinplate are produced each year, and most of it is used to manufacture many billions of food containers. The nontoxic nature of tin salts makes tinplate ideal for use with beverages and foods. 

The base metal for tin-plating is low carbon steel. The term tin-plate is reserved for a low carbon steel strip coated on both sides with a thin layer of tin. In recent years, the hot dipping process for tin plating has been replaced by electroplating because of the improved film properties obtained by the latter process. 

Spring steel fasteners are usually made from close annealed carbon steel strip, and after being formed are hardened and tempered. A conventional sheet metal screw or self-tapping screw is used with the basic type of spring steel fastener, which has an arched base and two arched prongs (Fig. 5).

Properties. The properties of plain carbon steels are governed principally by carbon content and microstmcture. These properties can be controlled by heat treatment as discussed. About half the plain carbon steels are used in the hot-roUed form, although increasingly the property combinations are enhanced by controlled cooling following the last stand of the hot mill for stmctural shapes, sheet, and strip. The other half are cold-roUed to thin sheet or strip and used direcdy or with an annealing treatment such as described. 

Tin is used in various industrial appHcations as cast and wrought forms obtained by rolling, drawing, extmsion, atomizing, and casting tinplate, ie, low carbon steel sheet or strip roUed to 0.15—0.25 mm thick and thinly coated with pure tin tin coatings and tin alloy coatings appHed to fabricated articles (as opposed to sheet or strip) of steel, cast iron, copper, copper-base alloys, and aluminum tin alloys and tin compounds.

The anodes are used high carbon steel band saw blades (Sandvik) cut into strips approximately 8" long. The cathodes are aluminum wire pounded to a thickness of 0.1mm. 

Because of the many types of rolled and forged steel products used in industry, basic specifications are needed to designate the various types. The American Iron and Steel Institute (AISI) has set up a series of standards for steel products. However, even the relatively simple product descriptions provided by AISI and shown in Table 2 must be used carefully. For instance, the AISI 1020 carbon steel does not refer to all 0.20 percent carbon steels. AISI 1020 is part of the numerical designation system defining the chemical composition of certain standard steels used primarily in bar, wire, and some tubular steel products. The system almost never applies to sheets, strip, plates, or structural material. One reason is that the chemical composition ranges of standard steels are unnecessarily restrictive for many applications. 

A spherical carbon-steel storage tank has an inside diameter of 30 ft. All joints are butt-welded with backing strip. If the tank is to be used at a working pressure of 30 psig and a temperature of 80°F, estimate the necessary wall thickness. No corrosion allowance is necessary. 

Overhead vapor from the CD column (1) is condensed and returned as reflux after removing propane and lights (P). The CD column bottom section strips benzene from cumene and heavies. The distillation train separates cumene product and recovers polyisopropylbenzenes (PIPB) and some heavy aromatics (H) from the net bottoms. PIPB reacts with benzene in the transalkylator (2) for maximum cumene yield. Operating conditions are mild and noncorrosive standard carbon steel can be used for all equipment.
