Fluted, Square or Round Ingot Moulds: How Mould Design Controls Cracking and Segregation

by

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

How to Choose the Right Forging Ingot Size: M1.5 to M23.5, Forging Ratio and Real Yield

by
How to Choose the Right Forging Ingot Size: M1.5 to M23.5, Forging Ratio and Real Yield

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: How Low Hydrogen Prevents Flaking in Heavy Forgings

by

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

Alloy Steel for the Valve and Oil Field Industry: ASTM A182 F11, F22, F91 and LF2 / LF3

by

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

IBR Approved Alloy Steel Industry : Meaning, Certification & Verification Guide For IBR Approved Alloy Steel

by

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

Forging Ingots vs Continuous Cast Billets: Which One Should Your Forging Shop Actually Buy?

by

Forging ingots vs continuous cast billets is one of the most common comparisons for forging shops in India. Choosing the right material depends on component size, forging ratio, cost, yield and application. Choose forging ingots when you need large cross-sections, heavy finished weights, open die forging, ring rolling or a high forging ratio. Choose continuous … Read more
