Steel Overview

Complete introduction and metallurgical analysis

1.3355 / BÖHLER S200 belongs to High Speed Steels and selection centres on red hardness, cutting-edge wear resistance and high compressive strength.

The principal recorded elements are C≈0.76%, Cr≈4.1%, V≈1.1%, W≈18%. Mid-range values support engineering interpretation and do not replace purchase limits.

The expected microstructure is highly alloyed tempered martensite with a dense distribution of primary and secondary carbides; delivery condition, section size, melt quality and processing history can change that state.

Comparison indices are hardness 98/100, toughness 35/100, impact 28/100, wear 98/100 and bending 56/100. These are internal indices, not standard test results.

The screening temperature range is 450–600 °C; strength or hardness loss, oxidation, exposure time and creep must be assessed separately.

A representative process route is careful staged preheating, high-temperature hardening, rapid controlled cooling and multiple tempering. Obtain actual temperatures, times and cooling media from the grade and product data sheet.

Manufacturing indices are weldability 12/100, machinability 26/100, corrosion resistance 20/100 and fatigue resistance 49/100; use them for screening only.

The principal risk is grinding cracks, overheating, carbide segregation or brittle failure under shock loading. Evaluate geometry, surface condition, environment and the governing failure mechanism together.

A similar name or calculated relationship is not proof of interchangeability; match chemistry, specification, condition, heat treatment and MTC.

Engineering conclusion: 1.3355 / BÖHLER S200 is a rational candidate when retention of cutting hardness at elevated edge temperatures matches the real load, environment and certified product condition.

Chemical Composition

Chemical composition and the role of each element

The principal recorded elements are C≈0.76%, Cr≈4.1%, V≈1.1%, W≈18%. Mid-range values support engineering interpretation and do not replace purchase limits. Composition is shown for screening and traceability. The current purchase standard and the heat-specific MTC remain authoritative.

Element	Weight-percent range	Metallurgical role and effect
C	≈ 0.76 %	Carbon raises hardness, strength and carbide potential; excessive carbon can reduce toughness and weldability.
Cr	≈ 4.1 %	Chromium promotes hardenability and carbide formation and, at sufficient levels, corrosion or oxidation resistance.
V	≈ 1.1 %	Vanadium refines grain and forms stable carbides that support wear resistance and secondary hardening.
W	≈ 18 %	Tungsten forms hard carbides and supports hot hardness and abrasive-wear resistance in tool steels.

Data limits

Impact & Toughness

Toughness, impact and fracture behaviour

Impact resistance is indexed at 28/100 and toughness at 35/100. These are not Charpy or Izod energy values; temperature, orientation, geometry and actual microstructure govern component behaviour.

28/100lowComparison index

Microstructure, hardness and grain size influence impact tolerance.
Sharp radii, notches and surface defects reduce fracture resistance.
Test temperature, specimen direction and section must be identified.
For critical parts, accept impact energy only from a documented test of the same condition.

Temperature & Creep

Service temperature, thermal stability and creep

Temperature behavior depends on grade family and heat treatment; HSS/hot-work grades are designed for higher hot-property retention. 450–600 °C is a screening range or sourced limit according to its evidence label. Check strength loss, oxidation, creep, exposure time and environment.

Continuous service

450–600 °CEngineering guidance

Review the limit against strength or hardness loss and exposure time.

Intermittent service

Do not assign an intermittent limit without product-specific source data.

Tempering and phase stability

Working and coating temperatures must remain compatible with the tempering condition and required microstructure.

Oxidation and environment

Oxidation or corrosion may become limiting before the strength criterion.

Relative creep resistance63/100Comparison index

The relative creep index is 63/100 (moderate). It is not an allowable creep stress or rupture-life value.

Do not select this grade for long-term static high-temperature loading from the internal index alone.

Engineering Conclusion

Engineering conclusion and selection recommendation

1.3355 / BÖHLER S200 is worth evaluating when the principal need is retention of cutting hardness at elevated edge temperatures. Internal indices of hardness 98/100, toughness 35/100, impact 28/100 and wear 98/100 must be aligned with the real failure mechanism. The leading risk is grinding cracks, overheating, carbide segregation or brittle failure under shock loading. Final approval requires the current standard, product form, dimensions, delivery condition, heat treatment and heat-specific MTC.
