Meaning of "cr content"
CR content: Stands for 'Content rating' or 'Carbon content'. 'CR content' in the context of digital media refers to the classification or rating assigned to content based on its suitability for certain audiences or platforms. In a material science context, 'CR content' may refer to the carbon content of a substance

cr content
Cr content should be high in order to achieve good corrosion resistance.
This effect increases with increasing Cr content of the steel.
A too low Cr content will reduce the corrosion resistance.
The segregation behavior of B is affected by the Cr content.
Too high Cr content results in a sintered material which is too brittle.
Accordingly, in the present invention, a Cr content and an Mo content are suppressed.
The Cr content is preferably optimized for the use temperature of the steel.
Furthermore, an increase in the Cr content leads to an increase in the alloy cost.
Therefore, to enhance the creep strength, it is effective to restrict the Cr content.
An excessively low Cr content can not attain the above effect.
From the viewpoint of increasing cold workability, the Cr content is preferably low.
But an excessive Cr content makes the steel brittle and lowers its oxidation resistance.
Therefore, upper and lower limits on the Cr content are preferably set.
As the Cr content increases, corrosion resistance can increase.
The appearance of highly ordered intra-mitochondrial inclusions correlates with a low intracellular total Cr content.

The thickness of the low Cr content complex oxide film is preferably 20 nm or less.
Cr content shall be controlled not less than 15 mass % for assurance of corrosion resistance.
To obtain a sufficient strength after sintering a Cr content of 2.5 % or higher is preferred.
If the Cr content is too low, the aforementioned effect can not be obtained.
In order to have essential corrosion resistance, the Cr content must be 16 mass % or more.
However, the percent Cr content at which those peaks appear differs with the manufacturing conditions.
FIG . 2 is a diagram showing the relationship between, a Cr content and a Mn content ; and hardenability.
As the Cr content is increased, the Ni content is correspondingly decreased.
Accordingly, a contact resistance value lower than 316L was obtained despite a high Cr content.
If the Cr content is less than 24 %, a sufficient corrosion resistance can not be attained.
The lower limit of the Cr content is preferably 18 %.
However, a Cr content of more than 35 % causes the hot workability to be markedly deteriorated.
The upper limit of the Cr content is set to be 25 %.
If the Cr content is too low, the above-described effects can not be achieved.
Hence, the upper limit of Cr content is preferably 1 %.
As the Cr content increases the minimum amount of ( C + N ) required increases.
The corrosion resistance is ensured by Cr content at 10 wt. % or more.
Cr content of 17.0 % or more is necessary in order to achieve good corrosion resistance.
In this regard, an upper limit of Cr content is determined at 20 mass %.
A minimum Cr content was specified as 0.1 % to sufficiently exhibit these advantages.
In order to achieve these effects, the Cr content is preferably 0.3 % or more.
When a Cr content is over 1.0 %, an effect to improve the strength is saturated.
However, the ductility decreases when the Cr content exceeds 40 %.
However, a Cr content exceeding about 1.0 % causes deterioration of ductility and weldability.
The preferable upper limit of the Cr content in the welding material is 24.5 %.
When Cr content exceeds 2.00 %, much martensite structure harmful to wear resistance and ductility occurs.
To secure the required corrosion resistance, the Cr content must exceed 26 %.
On the other hand, if the Cr content exceeds 1.0 %, cold workability is significantly decreased.
Sufficient oxidation resistance can not be achieved in the case where Cr content is less than 12.0 %.
However, if the Cr content is less than 10 %, the above effects are not obtainable.
For these advantages to be exhibited, the Cr content is 0.2 percent by mass or more.
