How Reliable 4140 Plate Supplier Should Be ?

How to Define a Good 4140 Plate Supplier ? 

First, the supplier should be experienced about the 4140 steel grades as per standard of ASTM A29 standard. The chemical composition and other property should be as per standard. This is the basic.

Second, if the supplier keeps 4140 steel plate stock with complete 4140 plate sizes / thickness or not. For example, 4140 sheet, 1.5mm thickness, 5 tons,  12mm, 6tons, 20mm, 5 tons… Then when anytime, customer need different4140 steel sizes with fast delivery, the supplier could process the order in very short time and delivery. Besides, when customer needs 4140 flat bar with different sizes, the supplier should be equipped with band saw to cut to width according to given spec and quantity. Like Otai, there is around 1000 tons stock of 4140 steel plate for customer’s choose.

Third, if the 4140 plate supplier is also able to supply material with different heat treatment condition and hardness, it would be good. Usually, it is usually supplied as 4140 hot rolled condition. Most of stock materials are hot rolled 4140 plate / flat bar. But some customer also need 4140 annealed plate, or Q+T plate with higher hardness. So, if the supplier could supply all different 4140 plate steel. It would be good for customer.

Fourth, if the price of 4140 plate material would be also good. It would be perfect. Or there would be regular 4140 steel plate for sale, it would be much attractive.

What You Should Care for 4140 Steel Material ?

Because it’s very common for 4140 round bar, but it’s not that popular for 4140 steel plate or 4140 flat bar. So, it’s not that easy to find a reliable 4140 steel plate supplier. But when you find it, you should care about something:

Hardness: Hardness of different condition of 4140 plate. Generally, the 4140 annealed plate hardness is max 255HB, while the quenched and tempered (Q&T) plate 28-32HRC (280-320HB). So, when you have requirement of hardness, you should make it clear to supplier, to avoid the wrong material condition.

Properties: When you have special mechanical properties, you would need heat treated plate for sure.

Equivalent: There are 4140 steel plate equivalent steel grades, that is, 42CrMo4 / 1.7225 plate or SCM440 plate. You would need to specify 4140 grade if you don’t accept equivalent. You could see the difference in this post 4140 | 42CrMo4 | SCM440.

4140 Shaft for Sugar Cane Machine

Customer needs 4140 Shaft for Sugar Cane Machine

Today, there is a customer’s forged round steel of 4140, and it has to do Q + T and car light state. The required diameters are all 300mm or more. Then we asked the customer about the purpose of the product he inquired about. The customer said that the round steel he inquired about was used as the main shaft of the sugar cane machine. It happens that we have provided those kind of shafts to many foreign customers, especially customers in the Americas, who also use this large round steel as the mechanical spindle. We send the picture records to the new customers.

4140 Shaft for Sugar Cane Machine

Property for 4140 Shaft

Customers are very interested in the products we supply. At the same time, we also asked customers about the mechanical performance requirements and technical standards he wanted. The customer sent the technical standard requirements in time, and our engineers carefully checked the customer’s standard requirements, and confirmed them one by one before replying to the customers. Because this is a processing product, compliance with technical requirements is the most important. We have raised our objection in one of the customer’s technical requirements. The customer requires that the diameter tolerance should be plus or minus 1mm, however the common diameter tolerance for turned round bar is controlled to be +/- 2mm to +/- 5mm. After the customer has heard our technical advice, the customer can also accept the conventional diameter tolerance that we can do. After the technical review is confirmed, the customer will ask us to make a quotation, and then do further review. But the client said that if it’s technically approved, it should be smoother later.

Important Things for those 4140 Shaft

  • Usually, we supply turned surface with desired tolerance.
  • The heat treatment is usually required as Q+T (quenching & tempering) or  N (normalized).
  • Fixed length is required according to customer’s final use.

We are glad to offer you complete solution for those 4140 shaft for sugar cane machine requests. Contact us anytime.

4140 Round Bar h9 Tolerance

MOQ of 4140 Round Bar h9 Tolerance

Today, one customer wants to buy some round steel bar 4140 material and h9 tolerance. But the quantity required is only 500 ~ 1000KG per size. This quantity can not meet the minimum order quantity of each size. Therefore, we told customer there is minimum order quantity of two tons each size. Because the stock materials are hot rolled, we need to do cold drawing to achieve h9 tolerance.

For cold drawing, if the order quantity is too small, there is no way to arrange cold drawing processing. Therefore, there will be a minimum order quantity of two tons per size. But this is the first case, which is for small batch orders.

In addition, the second case is that if the total number of orders exceeds 50 tons, then we could arrange cold drawing directly after steelmaking. In that case, there is no minimum order quantity of two tons per size.

At the beginning, the customer did not understand it, but after we explained it to him, he also understood that it was because of a limitation of production and processing. Then we quote to the customer according to the minimum order quantity of two tons. Now the customer is still waiting for the project approval, I hope there will be positive feedback later.

Further Machining to Achieve h9 Tolerance

By the way, whenever there is a diameter tolerance requirement, further machining must be required. The tolerance requirements specified by the customer can be achieved by cold drawing, or by peeling & turning or polishing. Also, there is generally a minimum order quantity. Because if the quantity is too small, theoretically, it’s not workable to do further processing. If customers only insist on small batches, the cost will be super high. That is totally feasiable.

Special Package

Another thing is that machined product will require additional packaging because of its relatively high diameter tolerance. Without special packaging requirements, the surface may be damaged during transportation. In that case, the surface tolerance may be out of customer requirements for damaged appearance. The general packaging at our side is to use wooden boxes to protect the surface of the product. If there are other customers with 4140 round bar h9 tolerance or other steel grades steel materials, welcome to contact us anytime.
