The Benefits of Using 1.2343 tool steel

Grade Cr Content Max Temp Toughness Equivalent 1. ~5% ~600°C Higher AISI H11 1. ~5.2% ~650°C Slightly Lower AISI H13

While both are hot work steels, 1. is slightly tougher, while 1. (H13) offers higher hot hardness.

How to Choose the Right Equivalent

When selecting an equivalent of 1. for a project, consider:

• Working Temperature: H13 (1.) is better for very high temps.

• Toughness Needs: 1. offers superior crack resistance.

• Regional Availability: AISI H11 is more accessible in North America.

• Finish Requirements: For polished molds, ensure high purity versions.

Where to Source 1. / H11 Tool Steel

Finding a reliable and experienced supplier is essential. Look for companies that:

• Provide full material certification (MTC)

• Offer both flat and round stock in multiple sizes

• Allow custom cutting or surface treatments

• Have international logistics support

Conclusion

1. tool steel is a premium-grade hot work tool steel widely used in forging, die casting, and extrusion tooling. Its most common equivalent is AISI H11, which shares similar chemical and mechanical properties. Other equivalents include SKD6 and BH11, depending on the region.

Both 1. and 1. steels are hot work tool steels. This article aims to compare these two types of steel in terms of their chemical composition, properties, and applications.

Chemical Composition

The chemical composition of a steel grade is crucial as it determines the steel’s properties and performance. Here are the chemical compositions of 1. and 1. steels:

Properties and Applications

• Toughness: Both steels are known for their toughness, but 1. is noted for its exceptional toughness and its ability to maintain its properties even at elevated temperatures. This suggests that 1. might be tougher, especially at high temperatures. Overall the difference in toughness is not significant and in literature, the amount of toughness of both grades mostly has been reported as equal.
• Strength: 1. has slightly better strength than 1. specifically at elevated temperatures.

• Thermal Properties: Thermal Expansion of 1. and 1. is almost similar but 1. thermal expansion is higher than 1.. On the other hand, the Thermal Conductivity of 1. is much lower than 1. and the reason for it could be finer grains

• Heat Checking: Both 1. and 1. have heat-checking resistance determined by conducting impact bending tests. 1. better resistance against Heat Checking makes it ideal in situations in which Heat Checking is the main failure cause.

Please note that the “better” steel depends on the specific application and working conditions. Both steels have their advantages, and the choice between them should be based on the requirements of the specific application.
