Q:Suppose that the hardness of steel is uniformly distributed, taking on values between 50 and 80 on the Rockwell B scale.Compute the probability that the hardness of a randomly selected steel specimen is less than 60. a..462b..333c..500d.2e..750 Question 8 Refer to question 7. Compute the probability that the hardness of a randomly selected steel specimen is between 70 and 75.a..167b..500c..063d..100e..

Suppose that the hardness of steel is uniformly distributed, taking on values between 50 and 80 on the Rockwell B scale. That would be... f(x) = 1/(80 - 50), 50 ≤ x ≤ 80 . . . . . 0 elsewhere Consider this following problem.. Compute the probability that the hardness of a randomly selected steel specimen is less than 60. Here, we have... P(x 60) Oh! Know that the mean and the standard deviation of the uniform distribution function are... ? = (a + b)/2 σ = (a - b)?/12 You should get... ? = 65 σ = 75 Now... P(z (60 - 65)/75) = P(z -0.07) Hence, you should get around 0.462. Good luck!

Q:Can steel coils be coated with fire-resistant materials?

Yes, steel coils can be coated with fire-resistant materials.

Q:looking for a good pocket knife. i keep going through these 440 steel pocket knives with every day work usage. this will be my 4th. even when i use a whetstone they stay sharp for a short period of time but the edge does not last, 440 is too soft! what is a good steel to look for in a pocket knife? also what are some good brands. ive been using gerber and buck sofar. if you could recommend me a few mid/small sized knives i would greatly appreciate it!

We hear it all the time and to be honest, it’s really, really hard to simply tell you what the ultimate pocket knife is. That’s because there are so many different knives on the market today and each one is suited to a different user and application. Of course there is a bunch of crap out there which we will endeavor to ensure you steer clear of but even after weeding those out you’re left with literally hundreds of choices from top quality manufacturers.

Q:I'm kind of confused as to how the difference between a stainless steel and blued steel firearm is sometimes only $20 or so. Isn't stainless steel fairly more expensive to manufacture than plain carbon steel? Are some stainless steel firearms simply stainless steel finished with carbon steel underneath?

I don't know that stainless can be laminated to steel very easily. Stainless is a little more expensive. The problem comes in that stainless is much harder to machine that normal gun steel. With laminated steel, you would still have the problem of machining the stainless. Occasionally firearms are nickle plated or barrels are chrome lined.

Q:What is the yield strength of steel coils?

The yield strength of steel coils can vary depending on the specific grade and composition of the steel. However, the typical yield strength of steel coils ranges from 300 to 600 megapascals (MPa).

Q:What are the common coil sizes available for steel coils?

The steel coil sizes available for different industries and applications vary. However, there are standard sizes commonly used across sectors. These sizes include coil widths of 36 inches, 48 inches, 60 inches, and 72 inches. In terms of coil diameter, the most common sizes range from 20 inches to 24 inches. Furthermore, coil weights can vary greatly depending on the type of steel and its intended use, ranging from a few thousand pounds to tens of thousands of pounds. It is important to note that these sizes can differ among steel manufacturers, so it is advisable to consult the specific supplier or industry standards to determine the available coil sizes for a particular steel product.

Q:What are the common uses of stainless steel coils?

Stainless steel coils are commonly used in a variety of industries for applications such as manufacturing automotive parts, appliances, construction materials, and HVAC systems. They are also utilized in the production of kitchen utensils, medical equipment, and food processing machinery due to their corrosion resistance, durability, and heat resistance properties.

Q:What are the different steel coil specifications?

There are various steel coil specifications available, including dimensions (thickness, width, and length), chemical composition, mechanical properties (such as tensile strength and yield strength), surface finish, and coating options. These specifications vary depending on the specific application and industry requirements.

Q:I am doing an assignment for my materials class, im not asking for the answer but just some help. I have the assignment finished and handed in but the teacher gave it back with one comment, he asked me to explain the grain growth in steel during hydraulic press bending. Im completely stuck, please help. Thanks.

when you press bend metal , its gets a little hotter at the point of the bend , its like bending a piece of metal back and fourth , the area of the bending gets hot .the distance between the atoms at that point expands thus, a small growth in the size of the metal

Q:How are steel coils inspected for thickness and width accuracy?

Steel coils are inspected for thickness and width accuracy using non-destructive testing methods such as ultrasonic testing and laser measurement systems. Ultrasonic testing involves sending high-frequency sound waves through the coil, and by analyzing the reflected waves, the thickness of the steel can be determined. Laser measurement systems use lasers to scan the width of the coil, providing precise measurements. These inspection methods help ensure that steel coils meet the required thickness and width specifications.
