Usage/Applications of Hot Rolled Spring Steel Bar 60Si2CrA with High Quality for Construction:

-Compared with Si-Mn spring steel under the similar condition of plasticity, 60Si2CrA have higher tensile strength, yield strength and hardenability.

-60Si2CrA is applied for producing springs with working temperature below 300~500℃. This type of spring can bear high stress, for example, governor spring, turbine steam seal spring, etc…

Packaging & Delivery of Hot Rolled Spring Steel Bar 60Si2CrA with High Quality for Construction:

-Packing Detail:

1, The products can be packed in bundles by steel wires.

2, The weight of each bundle no exceed normally 3 tons

-Marks: there are two types of marks. One is tag mark, for showing customers the specifications of products, company name and logo and other information required by customers. Other one is color marks. They are used to make the products more evident so that it’s easy for customers to distinguish them from other products at destination port.

-Delivery Detail: 30~45 working days after receive buyer’s T.T. or L/C.

Transportation:

-The products can be delivered by bulk vessel or by container. As for container, products with the length of 6m will be loaded in 20’ container, with 9m or 12m, in 40’ container.

-The maximum quantity of loading of container is 25 tons.

-The products are usually transported to the nearest port from the production place.

Payment:

-Invoicing on theoretical weight or actual weight as customer’s request.

-FOB, CFR or CIF.

-Terms of payment: T.T. or L/C at sight.

 

FAQ:

Q1: How soon can we receive the product after purchase?

A1: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q2: What makes stainless steel stainless?

A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q3: Can stainless steel rust?

A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.
