Overview P20 steel is a chromium-molybdenum alloy steel widely used in tooling applications, particularly in plastic injection mold tooling. Known for its excellent machinability, good polishability, and balanced mechanical properties, P20 is typically supplied in the pre-hardened condition (around 280–320 HB or ~30–36 HRC), making it convenient for mold manufacturing without the need for further…
1. Introduction EN8 carbon steel is an unalloyed medium carbon steel grade with good tensile strength. It is commonly used in applications that require higher strength than mild steel but do not necessitate the hardness or strength of alloy steels. EN8 is typically supplied in the untreated or normalized condition and can be heat treated…
1. Introduction EN-19 is a high-quality alloy steel grade predominantly known for its excellent mechanical properties. It belongs to the class of medium carbon, low alloy steel and is commonly referred to by its AISI designation 4140. With its combination of strength, toughness, and wear resistance, EN-19 is widely used in engineering applications where durability…
Overview Sri Lanka’s raw metal industry is a vital component of its light engineering and manufacturing sectors. The country is known for its foundry industry, which has roots tracing back to the second century BC. Modern developments have led to the establishment of various foundries specializing in the production of base metal products such as…
