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.
