The 1.2714 steel type is also known as X38CrMoV15-1 and DIN 1.2714. It is one variety of high-alloy martensitic stainless Steel. It gets its fame for its unmatched corrosion resistance properties, as well as high hardness. That being said, even its properties come with specific sets of challenges. They remain present throughout the manufacturing, as well as during the processing phase. Here's a briefing on each of the aspects.

The Challenges

A premier 1.2714 steel supplier in India directs that some of the challenges of using this variety are:

• High Hardness: This Steel inherently has a relatively high level of hardness. This makes it somewhat challenging to machine, grind and process. This means that the tool might wear away rapidly. So, this might require more frequent changes in tools, thereby enhancing the cost of production.
• Sensitivity of heat treatment: Right amount of heat treatment is essential to get the properties that you look for. Any inaccuracy in heat application can lead to varied microstructure, corrosion resistance and hardness.
• Susceptibility to Hot Cracking: While welding, this steel variety is more vulnerable to issues like hot cracking.  This is because of the high content of alloy that it has.
• Cost: Due to the high content of alloy, and also the need for specialized processing working with this Steel can be expensive.
• Welding issues: The high strength of the Steel and its hardness are likely to pose a challenge while welding. This can potentially lead to cracks or porosity.
• Warping and Distortion:  The strength and hardness of this Steel are likely to cause warping or distortion.
• Low machinability: The hardness and high strength of the Steel can reduce its level of machinability. This can increase tool wear. Hence it can be difficult to achieve the right level of tolerance.

The Possible Solutions

The issues that typically come with this variety of Hot Work Steel can be solved with a little bit of planning. You can consider:

• Tooling and Machining: Think of using ceramic or carbide cutting tools.  They can optimize the parameters that enhance tool life. Such aspects include cutting depth, feed and speed. You can also think of using cryogenic Machining. This can improve surface finish and also increase tool life. Also, use of coolers, which are heavy duty can help in chip removal, and also lessen down the tool temperature.

• Heat Treatment: Reputed steel tool manufacturers and suppliers like Kushal Metals give a lot of importance in optimizing the procedure of heat treatment. This minimizes the chance of warping and distortion, and help to achieve the needed properties.

• Specialized Welding: Using methods like post-heating and pre-heating can take care of porosity and cracks. However, it is also important to consider the optimal pre-heating and post-welding temperature and choose the ideal welding consumables. Together, it can help check porosity and cracking. Heat treatment after the welding session can further improve microstructure and reduce stress. You can also think of alternatives to Welding, such as adhesive bonding and Welding.

Conclusion

While you consider the important aspects of making the most of your experience with 1.2714 Steel, it is also important to consider the cost management question. So make sure to discuss with your steel manufacturer to decide whether this variety would work for your project.
