Часто задаваемые вопросы (FAQ)

What is the difference between C45 and 1045 steel?

C45 and 1045 are essentially the same material with different designation systems. C45 is the European designation, while 1045 is the American AISI/SAE designation. Both refer to medium carbon steel with approximately 0.45% carbon content.

Can Carbon steel C45 be welded?

Yes, Carbon steel C45 can be welded using various techniques including MIG, TIG, and arc welding. However, preheating (200-300°C) is recommended for thicker sections to prevent cracking, and post-weld heat treatment may be necessary for critical applications.

What is the maximum hardness achievable with EN8 carbon steel?

EN8 carbon steel can achieve hardness levels of 45-55 HRC after proper heat treatment (hardening and tempering). The exact hardness depends on the heat treatment parameters and section thickness.

Is C45 steel suitable for high-temperature applications?

C45 steel can operate at temperatures up to 400°C (752°F) without significant loss of mechanical properties. For higher temperatures, special heat treatment or alternative materials may be required.

How does C45 steel compare to stainless steel in terms of corrosion resistance?

C45 carbon steel has limited corrosion resistance compared to stainless steel. It requires protective coatings or treatments for corrosive environments, while stainless steel offers inherent corrosion resistance.

What cutting tools are recommended for machining C45 steel?

For machining C45 steel, use carbide or HSS tools with proper coatings. Recommended cutting speeds: 80-120 m/min for turning, 60-100 m/min for milling. Use appropriate coolant to manage heat generation and extend tool life.

Can C45 steel be case hardened?

Yes, C45 steel can be case hardened through processes like carburizing or nitriding. This creates a hard outer surface while maintaining a tough core, ideal for components requiring wear resistance with impact strength.

What is the typical delivery time for C45 steel orders?

Standard sizes are typically available for immediate shipping (1-3 business days). Custom sizes may require 5-10 business days, depending on specifications and quantity. Express shipping options are available for urgent requirements.
