- Description
- A semi-finished round cornered square alloy steel bar with a cross-section throughout its length. Sizes ranging from 95 mm square up to 250.7 mm square. The semi-finished round corned square steel bars of 37CRS4 are subjected to mechanical working by hot closed die forging, and this grade is used for crankshafts and mining forgings. The main molten steel production methods include melting raw materials using either an electric arc furnace or basic oxygen furnace melting of raw materials, ladle furnace refining, vacuum degassing, and the tundish adjustments to chemistry. After this stage, the steel solidifies through Continuous casting into oscillating moulds to produce blooms. These hot rolled blooms and ingots that feature smooth surfaces, which may be mill-finish, lightly scaled, or shot-blasted. During forging, the steel is heated above 1,175°C, fully converting its crystalline structure to austenite. This process eliminates previous micro-structures present in the imported steel. These may reform during cooling but are typically refined compared to the original as-rolled or as-cast structures. For precipitation hardening grades, forging at high temperatures also acts as a solution treatment, dissolving precipitates formed during rolling. Initially, imported steel has limited useful mechanical properties. The desired properties are established during forging or via traditional heat treatments post-forging. Imported bars arrive in a round cornered square cross-section, but none of these shapes remain in the finished product.

- Justification
- Classification has been determined in accordance with the following: For the purposes of determining the commodity codes within which goods most appropriately fall, reg 3 (1) of The Customs Tariff (Establishment) (EU Exit) Regulations 2020 sets out that the rules of interpretation contained in the following have effect – a. Part Two (Goods Classification Table Rules of Interpretation) of the Tariff of the United Kingdom (Reg 3(1)(a)); and b. Notes to a section or chapter of the Goods Classification Table (Reg 3(1)(b)). General interpretative rules (GIRs): GIR 1 has been used to classify this product by the terms of heading 7224 - Other alloy steel in ingots or other primary forms; semi-finished products of other alloy steel GIR 6 has been used to classify the goods to subheading level 722490 - Other than ingots and other primary forms; Other than of tool steel 8-Digit code 72249007 - Other than elsewhere specified in this subheading Also classified in accordance with: Chapter Note f to Chapter 72 Chapter Note ij to Chapter 72 Harmonized System Explanatory Notes (HSEN's) to chapter 72 (IV) (C) Harmonized System Explanatory Notes (HSEN's) to heading 7224
