These values depend solely on the type/application code given in the first part of the code and are so numerous as to be impossible to indicate here. Additional symbols are separated from the main code by the plus sign (+). The most common additional symbols are the impact and temperature codes for structural steels, category 1 - Sxxx.
In the recent past, HSS was commonly available in mild steel, such as A500 grade B. Today, HSS is commonly available in mild steel, A500 grade C. Other steel grades available for HSS are A847 (weathering steel), A1065 (large sections up to 50 inch sq made with SAW process), and recently approved A1085 (higher strength, tighter tolerances than ...
In the case of steel products such as sections, bolts and fabricated steelwork the CE Marking demonstrates that the product complies with the relevant harmonized standard. [7] For steel structures the main harmonized standards are: Steel sections and plate – EN 10025-1; Hollow sections – EN 10219-1 and EN 10210-1; Pre-loadable bolts – EN ...
The process of assigning HS codes is known as "HS Classification". All products can be classified in the HS by using the General Rules for the Interpretation of the Harmonized System ("GRI") that must be applied in strict order. HS codes can be determined by a variety of factors including a product's composition, its form and its function.
The tariff schedule has 99 chapters under 22 sections, and various appendices for chemicals, pharmaceuticals, and intermediate chemicals for dye.Raw materials or basic substances generally appear in the early chapters and in earlier headings within a chapter, whereas highly processed goods and manufactured articles appear in later chapters and headings.
High-strength low-alloy steel (HSLA) is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel. HSLA steels vary from other steels in that they are not made to meet a specific chemical composition but rather specific mechanical properties.

On certified steels, the plates are marked with the grade and a preceding "AB/", e.g. AB/A etc. [3] Yield point for all ordinary-strength ABS steels is specified as 34,000 psi (235 MPa ), except for ABS A in thicknesses of greater than 1 inch (25 mm) which has yield strength of 32,000 psi (225 MPa), and cold flange rolled sections, which have ...
