What makes SAE 4140 steel ideal for industrial applications?
SAE 4140 is a chrome-molybdenum alloy steel (0.95Cr 0.20Mo) offering exceptional strength, toughness, and wear resistance. Its balanced composition provides excellent hardenability and fatigue resistance, making it ideal for automotive components, aerospace parts, oil & gas equipment, and heavy-duty industrial machinery.
What forms of SAE 4140 steel do you supply in Michigan?
As a Michigan-based supplier, we provide comprehensive SAE 4140 steel products including bars, mechanical tubing, sheet, strip, plate, forgings, and rings. All products meet AMS specifications and military standards, with various heat treatment options including normalized and annealed conditions.
What AMS specifications do your SAE 4140 products meet?
Our SAE 4140 steel meets multiple AMS specifications including AMS 6349, AMS 6381, AMS 6382, AMS 6390, AMS 6395, and AMS 6529, as well as military specification MIL-S-5626. Each specification is tailored for specific applications, forms, and heat treatment conditions.
What's the difference between normalized and annealed 4140 steel?
Normalized 4140 steel offers higher strength and hardness with fine-grain structure, ideal for applications requiring maximum mechanical properties. Annealed 4140 provides improved machinability and formability with reduced hardness, making it suitable for parts requiring extensive machining or forming operations.
