In the era of commercial wrought iron, blooms were slag-riddled iron castings poured in a bloomery before being worked into wrought iron. In the era of commercial steel, blooms are intermediate-stage pieces of steel produced by a first pass of rolling (in a blooming mill) that works the ingots down to a smaller cross-sectional area, but still greater than 36 in 2 (230 cm 2).

PASKAL: The Movie is a 2018 Malaysian Malay-language military action film directed by Adrian Teh and produced by Asia Tropical Films. It stars Hairul Azreen, Jasmine Suraya Chin, and Tiger Chen. It was inspired by the elite Royal Malaysian Navy (RMN) force named PASKAL (Pasukan Khas Laut).
Tool steel is any of various carbon steels and alloy steels that are particularly well-suited to be made into tools and tooling, including cutting tools, dies, hand tools, knives, and others. Their suitability comes from their distinctive hardness , resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated ...
Tool steel 1.2344 (also known as AISI H13 steel or just H13 [1]) is a tool steel grade standardised for hot working. The main feature of this grade is the combination of alloyed elements of chromium, molybdenum and vanadium, Cr-Mo-V, which provides a high wear resistance to thermal shock. It is well known as for its great strength, and heat ...
The beginning of simulation in casting started in the 1950s when V. Pashkis used analog computers to predict the movement of the crystallization front. [5] The first use of digital computers to solve problems related to casting was carried out by Dr K. Fursund in 1962, who considered the penetration of steel into a sand mold. [6]
In 1945, Associated Swedish Steel was created together with four other major Swedish steel producers to sell steel to the new markets in South America, Africa, Middle East and Asia. In 1976, Uddeholm bought the whole of ASSAB and since 1 April 2011, it is fully integrated in Uddeholms AB with the exception of ASSAB Pacific Pte Ltd. [ 1 ]
Steel castings are used when iron castings cannot deliver enough strength or shock resistance. [1] Examples of items that are steel castings include: hydroelectric turbine wheels, forging presses, gears, railroad truck frames, valve bodies, pump casings, mining machinery, marine equipment, turbocharger turbines and engine cylinder blocks.

Castability is the ease of forming a quality casting. [1] A very castable part design is easily developed, incurs minimal tooling costs, requires minimal energy, and has few rejections. [ 2 ] Castability can refer to a part design or a material property .
