Steel Hardness Converter: Rockwell C to Tensile Strength, HRC to BHN Calculator & Charts



Convert Rockwell C (HRC) to Brinell (BHN), Vickers (HV), and tensile strength (ksi/MPa) instantly using ASTM E140 tables—essential for verifying 17-4PH, 4140, tool steels during heat treatment and QC.  

Nifty Alloys provides formulas like Tensile (ksi) ≈ 0.5 × HRC + 90, HRC to BHN charts (HRC 40 = 375 BHN = 1172 MPa), and Excel tips for engineers matching mill certs to drawings.

17-4 PH vs 316 Stainless Steel – Which is Right for Your Project?

Image
    Choosing the right stainless steel can decide whether your project delivers long‑term performance or fails early. 17-4 PH offers  very high  strength and hardness, while 316 stainless steel is known for superior corrosion resistance in seawater and chemical environments.   To see detailed comparison tables for composition, mechanical properties, corrosion behavior, applications, and cost—and clear guidance on when to choose 17-4 PH versus when 316 is the safer  option —read the full guide here:  17-4 PH vs 316 Stainless Steel – Which is Right for Your Project?

Spring Steel: Composition, Grades, and Properties

Image
Spring steel is a family of high‑carbon and alloy steels designed to flex under load and return to their original shape, making them ideal for springs, clips, and high‑stress components. Its chemistry is tuned for high yield strength, excellent fatigue resistance, and good toughness, with popular grades like 55Si7, 60SiCr7, SUP9, and 5160 widely used in automotive and industrial applications.   To see detailed composition tables, equivalent international grades, mechanical properties, and key industrial uses—from leaf springs and suspensions to tools and machinery—read the full guide here:  Full article on Nifty Alloys:   https://niftyalloys.com/blogs/spring-steel
