1000 & 1045 Steel Machined Parts
Balancing strength against machining cost is a recurring challenge for buyers ordering large production volumes. 1045/1045F carbon steel machined parts address it directly. SAE 1045 and 1045F are medium tensile carbon steel alloys that combine good strength with a reliable heat-treating response, making them a dependable choice for high-output runs.
E.J. Basler manufactures 1045 and 1045F parts at production volumes of 100,000+ pieces, with the capacity and process control to keep specs consistent over long programs.
Properties and Benefits of 1045 & 1045F Medium-Carbon Steel
1045 is a medium-carbon steel with roughly 0.45% carbon, which gives it noticeably higher strength than low-carbon grades while remaining machinable. The free-machining 1045F variant adds sulfur to break chips cleanly and raise cutting speeds, making it well suited to high-volume turned-part work.

Frequently Asked Questions
What is the difference between 1045 and 1045F carbon steel?
1045 is a standard medium-carbon steel valued for its strength and heat-treatability. 1045F is a free-machining version with added sulfur that runs faster on the machine and produces better chip control. Choose 1045F when cycle time and finish matter most and 1045 when maximum cleanliness of the alloy is required.
Can 1045 carbon steel be hardened?
Yes. 1045 responds well to flame and induction hardening to produce a hard, wear-resistant surface, and it can also be through-hardened by quench and temper. This makes it a strong choice for parts that need higher hardness after machining.
What tolerances can E.J. Basler hold on 1045/1045F machined parts?
On Swiss, Hydromat, and multi-spindle platforms, tolerances within plus or minus 0.0005 inches are routine. Tighter tolerances are achievable with grinding and other secondary operations.
Is 1045 a good fit for parts that will be welded after machining?
1045 is weldable but its medium carbon content increases the risk of cracking, so preheating and post-weld treatment are often required. For parts that see significant welding, a lower-carbon grade like 1018 is usually the easier choice.
Can E.J. Basler handle production runs under 100,000 pieces?
Yes. Our high-volume contract manufacturing center is optimized for runs of 100,000+ pieces, and we also accept smaller volumes when the part fits our process strengths.
