ZG45 China Steel 1

[TRRMan]

Does anyone know the US equivalent for ZG45 China Steel.

ZG45 is a coating weight specification. It doesnt tell us anything about the substrate material.

We need more information.

Thanks

The only other detail that I have is that it's die-cast and has a compressive strength of 310-570.
Thanks

Hmmmmm... Ah... Google comes through again....:

All I did to get this info was google it a few different ways.....

The full description of the new spec is:

China GB 5676 ZG310-570(ZG45) F cast steel, carbon
(courtesy of Maryland Metrics)


ZG310-570
Carbon: 0.50 Manganese: 0.90 Silicon: 0.60
Yield strength: 310 MPa
Ultimate Tensile Strength: 570 MPa
% of some measured value (possibly elongation): 15%
% of some measured value (I have no clue): 21%
A[sub]K[/sub] in KJ/m^2: 300 (possibly impact values?)

ZG45
Carbon: 0.42~0.52 Manganese: 0.50~0.80 Silicon: 0.20~0.45
Yield: 320MPa
UTS: 580 MPa
Again here's the three values that I dont know what their Variables translate to:
12%
20%
300 KJ/m^2


Here is the webpage I got this info from:

I love materials science!

Nick,

I will jump out on a limb and guess that those mystery numbers are elongation, reduction in area, and Charpy impact energy.

Cory

Thats what I'd thought, but didnt want to mis-lead. Wonder if I'll get a star?
