Buying tips

Buy it with confidence.

What to ask for in the RFQ and check when goods arrive.

  • Ask for mill test certificates (EN 10204 3.1) traceable to the heat number.
  • Specify heat treatment and hardness, and check hardness on arrival.
  • Agree corrosion protection for sea freight: oil, VCI packing, primer or plating.
Carbon and alloy steel questions

Straight answers.

Anything else, ask us directly. A principal replies, not a bot.

anirudh@sourcesquid.co

Are Indian steel grades equivalent to European grades?

Indian Standard (IS) grades have close equivalents in EN, DIN and ASTM. Put the grade you need on the drawing and ask the supplier to confirm the equivalent and supply certificates.

Where are steel forgings made in India?

Pune–Chakan, Ludhiana, Rajkot, Faridabad and Hosur are the main forging clusters, with Mandi Gobindgarh and Jamshedpur close to steel supply.

How do I check the steel grade of delivered parts?

Review the mill certificates and run spot checks with optical emission spectrometry (OES), which also measures carbon.
