Quick answer Navratri, Dussehra and Diwali fall across September and November and bring overlapping short shutdowns – not one clean holiday but several partial stoppages stacked close together – across melt shops, transporters and labour throughout the NCR–Rajasthan manufacturing belt. The reliable way to avoid a supply gap is to place your Q3 order 3–4 … Read more
Quick answer Free-cutting steel (EN1A, SAE 1117, EN8DM) has controlled sulphur – and in some grades, lead – deliberately added to make the steel break chips cleanly and machine faster on automatic lathes. The trade-off is lower weldability and slightly reduced toughness compared with an equivalent plain-carbon grade, which is why free-cutting steel is chosen … Read more
200 mm round as-cast billets are now part of Kesari Alloys’ billet and bloom range, alongside the existing square sections from 100×100 to 250×250 SQ mm. Supplied as-cast at approximately 240 kg per metre, these continuous cast round billets are designed for seamless tube and pipe production, round-bar re-rolling, and shaft or ring forging applications. … Read more
When sourcing forging ingots, billets or blooms in Delhi NCR, check ten things before you compare price: certifications, grade range, size range, melting route, heat number traceability, in-house testing, heat treatment capability, existing vendor approvals, lead time and freight cost. Proximity to your plant matters but only after the material is right. A cheap local … Read more
The mould does far more than hold the shape. It controls how fast and in which direction the steel solidifies, and that decides grain structure, the extent of centreline segregation, and whether the surface cracks. Fluted molds increase surface area and speed up heat extraction. Square moulds are the general-purpose choice for drawing down. Round … Read more
Choosing the right forging ingot size is not simply a matter of matching the ingot weight to the finished component. The size and profile of the starting forging ingot directly influence material yield, forging reduction, internal soundness, machining cost and the final inspection outcome. An ingot that is too small may not provide the required … Read more
Vacuum degassing in steel making is a critical secondary metallurgy process used to reduce dissolved gases in liquid steel, especially hydrogen, oxygen and nitrogen, before casting. Vacuum degassing (VD) exposes liquid steel to a vacuum so dissolved gases, mainly hydrogen, along with oxygen and nitrogen escape before the steel is cast. In heavy forgings, hydrogen … Read more
For valve and oil field forgings, grade selection is driven almost entirely by service temperature and environment. Use A350 LF2 / LF3 for low-temperature service, A182 F11 and F22 for elevated-temperature and hydrogen service in refineries, and A182 F91 for high-temperature, high-pressure steam and power applications. Where the medium contains hydrogen sulphide, the material must … Read more
EN31 SAE 52100 bearing steel is widely used for bearing races, balls, rollers and other precision components where high hardness and fatigue resistance are required. EN31 SAE 52100 bearing steel is a high carbon, high chromium through-hardening steel used for ball and roller bearings. It is known internationally as SAE 52100, AISI 52100 or 100Cr6. … Read more
IBR stands for the Indian Boiler Regulations, 1950, framed under the Indian Boilers Act, 1923. When a supplier calls itself an IBR approved forging ingots manufacturer, it means the mill and its material are recognised under those regulations for use in boilers and steam pressure parts, and that it can issue material certificates in the … Read more
